  1. Here are a couple of links to threads on this site regarding the installation of an aftermarket head unit. In order to install a doouble din unit you'll probably need the installation kit described which is available on e-bay. http://www.renntech.org/forums/index.php?s...616&hl=avic & http://www.renntech.org/forums/index.php?s...hl=kenwood+8120 I'd also suggest a search for other information on this site regarding the installation from which you will be able to determine if your skill sets match the task or rarther how much time it may require from you to do an install not to mention the broken parts that are inevitable in an endeavor like this. In my case I invested many hours or was it days? doing the research before I attempted the install. Like you I am not an audiophile which is why I kept the factory speakers which with the new amp and head unit sound great. In your case you might get by with a better quality top end Kenwood or Pioneer at around $1200 & use the head unit amplifier as opposed to installing a new amp. Just be aware that the specs on the HU output are measured at optimum & in reality are probably half of that when installed. You can check www.crutchfield.com for good info on units & requirements.

  2. As Loren points out it would be best to know what year your vehicle is as the latter models have the MOST optical bus. Essentially that means that you need to change the amplifier if you are changing the head unit which makes it more expensive. The speakers can be part of the new system or you can change them out at the same time. I kept mine. With that said installation is possible for a DIY but is not straight forward. I saved $1950 doing it myself which was a combination of purchasing the unit & the options from an authorized dealer on the web-a must for warranty as well as the factory rebate of $150 not to mention the high installation cost since it was a "996 Porsche". There are a number of good posts which you can search for installation info. Personally I have just completed the install of the lastest Kenwood DNX 9140 which has all the features you have described. It uses the Garmin nav system, voice command which helps if your car is manual & has built in bluetooth plus all the other bells & whistles. I have a rear view camera as an option. The Pioneer units that I looked at are also quite good. I'd start with a review of the factory web sites & then visit a store like Best Buy. One differance is the screen display which is larger on the Kenwood units since they do not have the manual switches adjacent to the screen. If you have it installed by an audio shop with speakers & options you may be looking at $3500-$4000 which is what I was quoted by several differant shops. The head unit alone at the low end with rebate will be $1200. Hope this helps. CMG
  3. Hi I just upgraded my system with a Alpine PDX5. In order to do so you must bypass the "MOST" optical harness which means a new head unit. I have an 04' 996 Targa with the Bose upgrade. The car has less than 14K miles so the factory amp should be in good shape. I had no problems with it. It is a Bose 6 channel amp. I also have the CDR 23 head unit. If you are interested send me a PM. Regards Cris
  4. I am interested in adding both interior & exterior self dimming mirrors to my 04' Targa. Can someone tell me if part # 993 731 982 00 which is a self dimming interior mirror will fit my car. I'd also be interested if anyone has the interior / exterior mirrors including the wiring available for sale. thanks CMG
  5. Attached is a picture of the package purchased from Pep Boys. There are several male plug sizes from which to chose which will allow connection to other female plugs in addition to the MOST harness. I've read a post about the Tyco plug but did not have time to source it out. This workes really well. Thanks for the diagram. In reviewing what I have there is no white/blue wire which is supposed to be on the cdr 23 wiring harness for the atenna output. I do have a white wire which seems to work when I connect the HU antenna output wire to it. Do you perhaps have the wiring diagram for the plug end? Thanks
  6. Ok so I have now installed the Kenwood DNX 9140 into my 04' Targa. A few points for those who might want to use the existing Bose speakers which I did. I have the M680 pkg (cdr 23 & 6 channel MOST amp) which gives me dash, doors, & rears as well as a sub by the passenger footwell. I am using an Alpine PDX 5 amp. The fronts- tweeter/midrange are 2 + ohms & the doors -midrange are also 2 + ohms. The rears are 4+ ohms tweeter/midrange & the sub is one ohm & is not separately powered. This drove me crazy since the documentation is all over the ballpark & of course this is a 996 & not a Boxster which I assumed would have much of the same wiring but--. Bottom line I connected the doors & dash in series which gave me 4 + ohms as measured at the harness. To do that I found that "Pep Boys Auto Stores" (national auto parts store) carries male connectors for the Bose premium sound system installed in many GM cars. I then connected these to the Alpine speaker wires & used heated shrink wrap insulation which was perfect to allow the connectors to be pluged into the existing female factory MOST harness without a matching male plug. I needed only two jumpers to connect the negative to positive wires of the Left & right dash/door speakers to enable the serial connection . Then I connected the other two wires positive & negative back to the amp for each side. That required only two channels & the rears took the other two channels of the Alpine. After a great deal of angst & a recommendation from Greg who has posted here & is an engineer as well as a former installer, I simply turned the gain way down on the Alpine for the unpowered sub channel & the system sounds just terrific. I can use all of the head unit controls & I have true 5.1. I also used an audiovox rear view camera which worked out beautifully. Finally there have been many posts on the AVIC3 & the bypass hack as well as the speed sensing wire. The Kenwood has no wire for speed & the bypass is super easy. It just require that the ground wire be connected to the parking sensor wire. I do not recommend placing the GPS antenna under the alarm sensor at the front of the windshield. IT is just way to much effort & you are likly to break something as I did. In retrospect I would place it under the plastic cover in front of the windshield by the trunk on the left side of the battery. It only needs not to be blocked by any metal going to the sky. I did this with the Sirius antenna & it works great. That will save hours of hassel. If you have a 6 channel system it would be even easier to get a new 6 +1 amp which eliminates wiring speakers in series assuming the amp is stable down to two ohms like the Alpine PDX 5. I also considered other alternatives such as wiring the doors & sub together which I may still do since the plug in harness has worked out so well. There are no wire splices with this setup. But at his point I am really happy with the sound. I also placed the voice command button in the ashtray which keeps it out of the way unless used & is also a very handy place for it. The microphone will eventually go where the factory mic is located behind the plug next to the instuments but for now it is zipp tied to the steering adjustment handle below the steering wheel. People tell me the bluetooth sounds like a high quality speaker phone on their end with no odd noises. Question: Is there a separate wire in the factory cdr 23 plugs for the antenna control wire from the head unit to be attached? Since there is no powered antenna I am wondering if the antenna might in fact be amplified thus requiring a connection to the head unit in addition to the plug in antenna? If someone could point me to a wiring diagram for the antenna and/or the cdr23 plug i'd appreciate it. Thanks Cris
  7. I put a hardwired wired audiovox lisense plate camera in over the w/e in preparation for installing a Kenwood DNX 9140 nav unit. Probably because I have an 04' Targa it was somewwhat differant so here is my update. The large groment as seen from the engine did not have a visable gromet above the main harness. However when seen from the inside there is a tube above the the main wiring harness which also has a tube entering the car from which the main harness wiring enters . I almost gave up before I pulled the insulation away to see that there really is an access thru the tube & into the gromet. Use a screwdriver to punch thru the gromet by using the tube as a guide for the screwdriver. The front seat belt by the door has a hidden screw which can be seen with a flashlight just at the rear of the seat belt that exits the door panel. Be sure to use a mag tool as you remove or it will be lost forever. There are also two other screws on the rear seat belt. One is accessed thru the little perforated plastic screen which pops off easily if one first removes the light socket & is at the top of the seatbelt. The second hidden screw is accessed after one pulls off the carpet which is just below the targa glass. It is at the rear of the seat belt plastic cover. Then one needs to pull up on the door panel after releasing the panel from along the window & floor. There is also a clip that points upward at the top of the forward seat belt. This turned into a royal PITA & I would never have done it if there had not been quite a few negatives about wireless rear camera's. At least I am safe with this setup & won't have my neighbor's baby monitor showing his cute face on my Kenwood.!! One last point is that I picked up the reverse wire (black & blue) thru a drain hole below the right taillight after I removed the taillight. That was really easy.
  8. "Thetino" con't -Loren sent to me the M680 upgraded Bose wiring from the MOST amp to theBose speakers. My front's & rears are 2.1-2.4 ohms. The Alpine PDX 5 will handle this configuration so I only need to figure out the door speakers/subs which I think are also in the door. The sub as you have indicated are one ohm & there is only two wires from the AMP (Brown/white - & white +. I have not taken the door apart but am relying on some of the posts as to where the sub is located & yes the wiring diagram indicates that the sub for your car is in the rear. I did remove the rt front & rear speakers to check the impedeance & wiring colors at both the speaker & at the MOST amp which are the same. What I am thinking is to wire the door speakers & subs together to increase the resistance to about 3.4 ohms (2.4 for the doors & one +- for the sub) & use the 5th channel to power those. Altenatively I could connect the fronts on the right side with the door speakers which would give me 4 + ohms for each channel. I think that is what you are suggesting. Have I got it right? Thanks much Cris
  9. Hi Thetino -In my 04 Targa with the upgraded Bose/MOST system I believe the midrange/tweeters are L & R on the dash while the L & R rear speakers are on the panels above the wheel arch That takes care of four channels. The subs are connected together in the doors which is the fifth channel. Many of the posts on this site have used the Alpine PBX 5 (2-4 ohms) which is why I bought it but in general aftermarket amp's are not stable below 2 ohms from my research. Hence my need to understand how to change the resistance or impedance on these speakers. I need the the "Wiring for Dummies" manual so that I can make this work.
  10. Thanks for the infor "thetino". Now, since I have the upgraded Bose system I believe the subs are in the doors. What I am wondering is exactly what one does to rewire the speakers from parallel to series. Would you be able to provide some guidence as to which wire goes where or if you simply jumper it in some way to change the resistence. Thanks much. Cris
  11. I have just purchased a Kenwood DNX9140 Nav/radio which I will be installing in an 04' 996 Targa with the upgraded Bose system. I'm intending to install it myself with the excellent articles on this site. To keep the install simple I want to use a wireless backup camera. However many installing dealers tell me it won't work as there will be interferance with the built in Parrot bluetooth. I need suggestions. Also How does one wire the speakers to change them from parallel 1 ohm to series with 4 ohms which seems to be required for the Alpine PBX5 amp. Lastly I will have the MOST amp & cdr 23 radio available for sale. Thanks
  12. It's been covered here before a few times. It is inside the front latch mechanism. Checked the sensor without success. Replaced the battery & voila! Light is off. Thanks much
  13. Thanks Loren. Are there instructions on the site for how to replace that micro switch that you can point me towards.? Cris
  14. I have an 04' 996 Targa with 12000 miles. It is new to me & the warning light for the hood/trunk was on when I purchased the car. After a few days of driving it went off but occationally re-lights & then goes off by itself. The battery is original & was in a low charge state when I purchased the car. I think the battery is still weak as the starter seems a bit slow. The dealer can't figure it out because the warning light is off when I take it to them. Is this a bad sensor or maybe a bad battery? How to test and/or fix the sensor would be appreciated. Thanks
  15. Hi Is your self dimming mirror still available. I am looking to add bothinterior & exterior self dimming mirrors to my 04 targa. Thanks
