Base standard radio in '05? Upgrade related

[OU Targa]

05 Cayenne base, standard original radio but wanting to upgrade so I can get touch screen bluetooth etc....

 

If I have the standard base radio, is that still a BOSE radio system (i.e. bose radio/amp, and MOST system?)

 

I know I don't have the upgraded sound system but am not clear if I still have the same upgrade issues regarding the MOST system (seems like everyone refers to it as the Bose Most system or similar so does that mean the standard equipment is NOT-BOSE).

 

Do I need the Most HUR 955 interface no matter what or is there a chance that the non-upgraded default radio does not require it?

 

Thanks

So, I'm going to update this thread as I go along in case anyone else needs this info going forward.  Although there are a lot of "radio" threads out there it appears that the vast majority of Cayenne buyers got the Bose sound package and thus I could not find conclusive information so here goes:

 

My '05 Cayenne base does not have the bose sound upgrade package and does not have an amp, just a fiber optic connected CD changer.  (translation: the MOST system in my Cayenne is only utilized for the CD changer)

 

Basics: if the speakers don't have the Bose logo you probably don't have bose.  The CD changer is located in the rear right cargo behind pull off panel.  My understanding is a non-bose amp would be located above the CD changer, that space can be viewed with a flashlight at the correct angle.

 

Original radio is the CDR-23 single din.  The back of the radio has three plugs (the top with three wires is the steering controls, the middle with 8 wires are the speakers, the bottom with three wires is the power/antenna).  In addition there is the antenna connection on the far left and a pair of FIBER OPTIC cables.  In this setup, the Fiber Optics cables run directly to the CD changer and that appears to be it.  I unplugged the fiber optic behind the radio and EVERYTHING works fine (radio, steering controls, dash still shows the station/song).  The CD changer obviously does not work but the CD slot on the head unit does work.  With 8 speaker wires in the back of the radio, it is evident these are running straight to the speakers, confirmed by the fact that no amp was found.  Also, called Becker and they confirmed that some becker units are not programmed to be used with an amp and most cars with an amp use a smaller yellow plug in the middle slot instead of the 8 speaker wires.

 

So for the Radio swap all I need is a new head unit and wiring harness, essentially it is now plug and play (thank you previous owner for only getting the basic radio option).

 

After some back and forth with a few car stereo and online sellers, the correct harness appears to be the Connects2 model CTSPO001 and is about a US$100 part.  This does include steering wheel controls which would negate the need to buy the US$50 ASWC-1 part.  (so essentially 50 for the basic harness and 50 for the steering controls)

 

The fiber optic plug will just be taped off behind the unit since I have no need for the CD changer (definitely not spending 500 for a fiber connection to tie it in), they also sell a fiber optic loop connection for 10-25 so I might do that just in case its better to have the fiber loop closed.

 

Other parts that are easily identified elsewhere: dash trim by Metra 95-9600, another one by Connects2 CT23PO01.  Antenna is 40-EU10 but it appears there are a couple almost identical to choose but know once hooked up.

 

Since the speaker wires are behind the head unit it would be easy to setup an amp in the front of the vehicle or possibly under the hood since any wires (power/speakers) wouldn't have to be routed all the way to the back of the vehicle.

 

Parts are all on order, will update when everything is connected.

Hi i have the 2006 Turbo S and the only thing that lets the car down in my opinion was the stereo looks dated no touch screen i wanted bluetooth connectivity for my phone and also my wifes and i also wanted usb and memeory card slots i have the Bose option and wanted to keep it that way so i opted after doing a lot of research for the Dynvin N6 it looks OEM and is the best upgrade i have done to my car it has everything you could want and more besides the sat nav is a vast impreovement also sounds much better than the old unit
