my electronics guys (benchmark motoring, bellevue, WA) recommend a new unit also if you're going to upgrade - because it's more advanced, has more features, etc.

no affiliation. i'm still pissed i can't add XM to my 2009

 

i added nav to my 06 car - simplest way is to buy oem nav kit from suncoast, it has all parts you may need. or you will need to search ebay - you need harness, cables, optical cables, horisontal dvd unit with matching version to your car electronics as pcm 2.1 exists in different internal versions and gps antenna. plus for install as i was told some drilling is required. it also matters if your trunk was pre-wired for nav or not.

 

All 997's come pre-wired, it is literally as simple as plugging in a lamp. Just a little more complicated to get to.

Suncoast Ric helped me out a lot when I got the unit off ebay. I have a Targa 4 and bought the correct unit (ends in 139 or 159) but they shipped me a C2 unit (ends in 137 or 157). The C2 unit still worked I just had to custom mount it horizontally instead of the factory vertical mount for the AWD cars...

Do you research on the net, there is a ton of info.

 

FYI

I did an aftermarket custom install of a Kenwood 8100 unit. Very nice system but.

1. If you have the Sport Chronos package you will still be able to use the stopwatch but you will not be able to review the stored lap times after the fact- this requires the original head unit.

2. You can no longer change the default for driving head lights.

If you want to use more than 4 speakers you will also need an amp. I went the standard 4 channel amp that came with the system. The sound is not as good but the navigation, Bluetooth phone, iPod, and USB chip interface are very nice.

Wow, looking at some of these links looks like I could have done it through the existing head unit for only a little more money. Damn!

 

Looking for confirmation on Nav DVD and PCM compatibility.
What is the origin/generation of a NAV DVD 997.642.137.02?
Will it work with a PCM 2.1 997.642.143.10?
(These will be going in a 2006 Cayman S with BOSE and CDC-4 changer)

Thanks!

 

I actually have a drive out if my C2 that I'm not using, I went with a pioneer.
I have the horizontal mounting bracket, drive and the nav disc.
PM if any one is interested.

Hi Chayce,

I haven't enough privileges for PM yet. I do need the horizontal bracket/holder for the NAV DVD drive and a navigation DVD! (What year version?) You can PM me, same id, renntech.org?

I am a NAV-TV dealer if anyone needs an iPod/phone interface to the PCM units.
