Porsche 911 (996) AVIC-Z1 Stereo Install Picture


Recommended Posts

I recently installed a new Pioneer AVIC-Z1 navigation system in my 2002 996. I took several pictures along the way in case others were interested in doing a simular project and can post them as needed. If you need help with your install of the AVIC-Z1, please go to AVIC411 and search the keyword: mivey911. If you post a message at AVIC411.com, I will be happy to try to help.

Izzy,

Thank you. The custom trim around the stereo is flush and color/texture matched. The stereo itself sticks out only slightly, but by design. In person, it really looks like it came from the factory (if the little 'Pioneer' logo said 'Porsche' it would not even be questionsed).

Complexity: Reasonably straight forward if you are comfortable with this type of stuff and have the wiring diagrams, etc (the stock radio (CDR220) wiring schematics are detailed in the back of the Radio owners manual that came with the car).

Estimated Install Time: 5 hours (going slow and being very careful)

Cost (all figures approxamate):

Pioneer AVIC-Z1: $1,500

Pioneer iPod Module: $50

Pioneer Bluetooth Module: $136

Antenna Adapter: $20

Climate Control Trim Piece (from Porsche to move Climate control to bottom shelf): $6

Metra ABS Blank Gridplate (for custom trim): $10

Wiring: $20

Rust-oleum Textured Paint for Plastic (Black): $4

Misc: $10

Mivey,

Looks great. I am also considering changing out the radio with a navi system.

For the wiring, were you able to find a wire harness that the original will plug straight into? If possible, I would like to avoid splicing or cutting into the wires...I'd like to be able to put the original Becker unit.

Thanks for your help...and great job...looks very clean.

Regards,

James

James,

I am not saying a wiring harness is not available, but I searched the world over (via the web) for a few weeks and never found one. I even started creating my own with parts from a Honda wiring harness I bought and epoxy. Ultimatly, I just bit the bullet and cut the wires (leaving enough wire with the plug so I could reattach it in case for some absolutly crazy reason I ever wanted to put the Becker back in (I had the same thought you have about putting it back to stock, but I will never do it, it looks so much better to me with the new system).

I think the plug is a standard ISO plug so I am sure it is available somewhere, but I could not find it and from what I found during my search, many others have had no luck either.

I will tell you though, If you go with a double din head unit like I did, you will need to cut the thin piece of plastic that separates the area between the climate controls and the Becker unit (if you go back to the Becker, this entire piece is easily replacable from your local Porsche parts department and probably not very expensive). Once you get past this, cutting the wires becomes less of a concern.

There is plenty of space behind the trim work so just about any double din unit will fit.

If you do decide to move forward with your Navi System, I am happy to help with any questions you may have.

MIVEY.

Mivey,

Thanks for sharing your experience. It does seem a bit strange that there a wire harness is not available. I have, however, found that a few posts that mention using a harnesses for Audi/VW.

I believe a Metra Wire Harness (70-1784) for VW/Audi is the part number mentioned by others. I havent got my hands on one yet..but will try to snap a picture when I do.

Anyways, the Navi unit I was interested in is actually a 1din Eclipse - Japanese equivalent of the AVN7000.

http://www.eclipse-web.com/7000index.html

I am still undecided about how it's going to look...particularly after seeing your install.

Thanks again for your feedback!

Regards,

James

James,

With the AVN7000 (or Japanese equivalent) being a 1 din unit, the install should be very easy. The Becker just slides out (using two small removal keys available for $2 from Becker, etc that go into the two tiny slots at the bottom right an left of the radio). You probably won't even have to disasemble the dash.

With some modification, a Wiring Harness for VW/Audi might work (See picture attached).

I also found reference to these guys www.nexxia.co.uk with regard to finding a plug-and-play adapter for the ISO plug. It is in the UK, but people have reported decent delivery times. The cost is going to be around $20 - $50US.

I have added some pictures of the stock Porsche plugs that connect to the Becker. I had the HiFi upgrade in my 996 so the yellow plug goes to the amp.

For my stereo install, every (almost, see below) wire I needed was included on one of the two standard plugs (continuous power, switched power, ground, illumination, speed senser, etc on the black plug and speaker / ground on the yellow plug). Many navigation head units also want to connect up to the Emergency Brake sensing wire. Because I used a 'bypass' to allow me to use the telephone and navigation function without pulling over, I did not need to hook this wire up (or look for it).

Edited in after Loren's question:

The only wire that was not readily available was the reverse sensing wire. I opted to not connect this wire as I do not use a back-up camera and from my research, no one has seen any negative performance with the navigation system when the reverse senseing wire is not connected. Thus far, I have not seen any negative side effects.

What about the reverse wire for the GPS?

Loren, good catch....

I opted to not connect this wire as I do not use a back-up camera and from my research, no one has seen any negative performance with the navigation system when the reverse senseing wire is not connected. Thus far, I have not seen any negative side effects.

I think I recall seeing a post where you guided someone to the point of connection for this.

Yes, there is a reverse connection under the left seat.

I think this looks super - form and fit look very very good. It would be great if you could write DIY including parts lists (and where to get them). If you do we'll get it into the DIY section so others can give this try too.

Loren,

I will try to work on a DIY for the entire install. In the mean time, here is the technique I used to create the custom faceplate.

How to Make Custom Faceplates Like the Pros.

This is the method I used and can be adapted for many types of faceplates (i.e. the piece of material that surrounds your stereo to fill in any gaps). This really applies when no dash kit / adapter is available for your make of car. I hope this is helpful to the do-it-yourself people out there.

NOTE: this is not intended to serve as a means to mount your stereo head unit. This is intended to help you finish the job with a clean look.

Porsche 996 Specific Parts:

  • A/C Panel Trim Piece - 996.552.339.00.01C (used when moving the A/C control to the bottom shelf in the 996)

Supplies:

  • Metra ABS Blank Gridplate (12" / 12") - Has a grooved grid on the back to make cutting straight lines very easy
    Rust-Oleum Textured Paint for Plastic (Black) or alternate color / texture
    Super Glue

Tools:

  • Razor Blade Knife / Utility Knife
    Very Fine-toothed saw / Japanese Dovetail saw (optional for faster cutting of the ABS plastic. Available at most home improvement stores)
    Medium and Fine Sandpaper sheets
    Orbital Sander with medium and fine sanding disks
    Mini Blowtorch (Only needed if you need to create a curved faceplate. Available at most home improvement stores)

Procedures:

If you need a flat faceplate (Applies to the 996):

1. Take horizontal and vertical measurements of the opening in your dash where your factory radio is currently installed (it may be easier if you have already removed your factory radio).

2. Lay the Metra ABS Blank Gridplate face down on a hard surface (use an old towel to keep it from sliding around).

3. Using the utility knife or Japanese Dovetail saw, cut the Metra ABS Blank Gridplate to size (or just slightly LARGER than the opening in your dash)

4. Position the newly cut piece in the dash using the sandpaper to sand it down to a perfect fit.

5. Measure the exact width and height of the part of your new stereo that will extend from the dash beyond the faceplate.

6. Using the utility knife or Japanese Dovetail saw, cut out the opening (or just slightly SMALLER than the size of your new stereo). The grid on the back of the ABS blank makes it easy to cut to any shape.

7. Position the newly cut piece around your new stereo using the sandpaper to sand it to a perfect fit.

8. If the Metra ABS Blank Gridplate finish does not already match your dash color or you want it to be a flatter black or other color, use the orbital sander to sand the glossy texture from the front of your new faceplate (again using an old towel to keep it from sliding around).

9. After you have sanded the faceplate, wash it in tap water to rinse off any dust and dry it thoroughly with a paper towel.

10. Using the Rust-Oleum Textured Paint for Plastic, paint the front of your new faceplate following the directions on the spray can. This will add a lightly textured finish to your faceplate (if your dash has a smooth finish, you can use non-textured paint for an exact match).

11. In addition to the snug fit around your stereo that will hold your face plate in place, you can use small strips of the leftover ABS material to build up the backside edges of the faceplate to enable it to 'seat' firmly against the area beside the radio. Use the super glue to join the pieces where necessary. 'Clips' can also be easily fashioned out of the ABS material if needed. NEVER permanently fasten the faceplate to the dash.

If you need a curved faceplate:

Follow the directions above but use a flexible sewing measuring tape to measure over the curves of your dash to get the width and length of the dash opening.

After you have cut the ABS plastic to size and sanded it (before painting), carefully use the mini blowtorch to lightly heat the ABS plastic where necessary to enable you to bend it to match the contour of your dash.

Large round PVC pipes / tubes, a drinking glass or other round surfaces can be used to achieve a good curve. The key is to be patient and test your technique on scrap pieces before doing your final bending work. Once cooled, the ABS plastic will keep its curve for the life of the car.

Finish your faceplate by washing it in cool water and painting it to match your dash color / texture.

Mivey,

Thanks for the pictures. Since this is the first time I install a head unit myself, how would it typically mount or fit into the 1 din space after removal of the Becker OEM unit?

I've already removed the OEM unit before...so that shouldnt be a problem. However, in your experience, would aftermarket unit "fit" right in without further modifications? I know there is a bracket included in the Eclipse package...however, have been wondering how this would connected.

Thanks again.

Regards,

James

thebairdybunch,

I was happily surprised to find a metal bracket that roughly frames a double DIN area behind the dash trim. This piece easily removes with two torx screws. I secured the unit to this using two brackets (one on each side) that I had left over from another project. To get the stereo head unit to sit at the right height I cut a small piece of MDF board / plywood for it to rest on (roughly 3/4 inch). There is an area that this piece just sits in perfectly without moving around so there is no need to fasten it in.

The attached pictures will give you an idea of what to expect behind the trim. Using this method, I was able to make minor adjustments (front to back) to the placement of the head unit. Once I got it right, I used a small right angle screw driver to tighten the brackets. If I need to pull the unit, all that is required is to remove the trim and the two original torx screws and the whole thing (unit and frame) slides out.

James,

Per your question regarding a single DIN install, If it is a standard single DIN head unit, it will likely slide right in without issue with a snug fit. Others who have changed the Becker for a single head unit may be able to tell you if a non-german unit will CLIP in as easily as the Becker. There are several Harmon-Kardon (now owns Becker) units that appear to fit perectly.

Firstly thanks for all the photos and the information on how to physically install - I just did the install and it was very simple especially considering that the ISO connect was a direct plug into the connector in My European car - I only had to connect one wire literally. I will get aroung to hiding the GPS under the alarm cover and also connecting the Mic in the dash in the near future.

As an aside I too have made some Jpeg images for the background of the unit - However looking at your images frankly yours seem much better - I used some from the Porsche website - But I was impressed with the picture you have selected.

I wonder if you would consider posting them for download ?

thanks

I installed the z1 in my 2000 996 a few months ago. I like how you used that bracket to hold the unit but i dont think i saw one in my 2000. i'm going to look again this weekend. Other then that it looks similar to my install. I'll try and take some pics of my install and post it here. (car is in the shop for oil leak)

i like the way you made your custom face plate. i'm going to try that this weekend...

Where did you put your mic? I hid mine behind that little pocket, left of the guages on the dashboard. It doesnt seem to work very good behind there.

thebairdybunch,

If you visit AVIC411.com you can download my background. There is a section dedicated to custom backgrounds (you can search the forum for Porsche and it will be among the few hits).

rychone,

I ran my mic along the top of the windsheild on the passenger side and secured it to the left of the little pod that holds the infrared sensors. I had read somewhere a year ago that the factory location was not the best spot (not sure if true) but I didn't want to go through the trouble to find out it would need to be moved.

I get good response in its curent location (I have a cab and it is still OK with the top down).

Juankimalo,

Thanks. The main reason I went with the Pioneer unit was the wireless Bluetooth Telephone and wired iPod connection capability. I like the fact that the Pioneer lets you store your music on its built in Hard Drive but with my iPod integrated to the unit I don't really use this feature much.

I am in the process of getting new speakers. I installed a JL e6450 amp and think I may have blown my factory speakers :).

For those who were looking for the wiring adapter for the ISO connectors, the Metra solution menitoned is good. I have access tosomething similar, as well as a plg-n-play solution for the upper connector block, too (where the CD changer pins, etc., are).

I prefer the "leave all the connectors in place" method of radio/accessory hook-up myself. But that tends to assume that you won't be the one driving the car until it's in the ground :drive:

"Climate Control Trim Piece (from Porsche to move Climate control to bottom shelf): $6"

Anyone have the part number for this piece??

Also, is it possible, is there a trim piece to move the "Climate Control" to replace the "CD Storage"?

Also, is there a trim piece to move the "CD Storage" to the bottom slot?

Thanks!!

Great job on the install! I especially like the faceplate that you did. I have all of the needed materials (although my ABS isn't gridded on the back, and I'm tempted to go that route for ease of construction), but haven't had time to get to it. I did the Z1 with LOTS of other changes going on at the same time (all the way down to getting different colored air inlets for the sides of my turbo, and learning how to fabricate slick CF parts on my own...did you know that those little air inlets are freaking $425/ea OEM? I almost died.).

Anyway, I wanted to thank you for the post. It got me inspired to clean-up and finish the audio aspect of my overhaul...something I had gotten a bit weary of after rebuilding my door panels to fit larger mids with a slightly slicker look than what came stock, as well as dealing with the 3sixty.2 interactive audio processor and the crappy reception my callers were getting with the mic in that hole in the dash next to the gauges (I found that creating a new 'grill' with more audio transperancy (sp?) helped a lot...that stock piece that covors the mic hole really killed the conversations quickly, not to mention the sound from behind the dash speaker bleeding into the mic and creating reverb...ugh).

I feel like I have lived and learned on this project like none other...the project being my entire car. My intention was and still is to post my experience here on Renntech.org. I just have to find the time to put it all together...I'm currently petitioning God to make the days longer, but I haven't been able to get enough signatures and he's running out of patience with my whole "just give me a little more time..." pleas.

Thanks for the great info!
