I just became a Porsche owner :D I bought a 2007 Porsche 911 C4S Coupe that came equiped with PCM2.1 with CD changer and telephone module; however, I recently discovered that it doesn't include the NAV system (no DVD drive in the trunk). Now, a few 911 owners that I know who have used the NAV system from Porsche claim that it isn't very user friendly, not touchscreen, a little slow, and not always very quick on calculating routes. I'm looking for some feedback from other 911 owners who have had the factory NAV and replaced it with a 3rd party unit or simply added a TomTom (or other hanheld GPS).

My car is a CPO car and I'm not interested in replacing out the factory CD/Stereo unit at this time as it will void the warranty coverage on the car; however, I would still like to know what other users think of the factory NAV (when updated to the latest version). Thanks to all.

On a side note, I'm trying to confirm if my PCM system is updated to the latest software/firmware:

PCM: 05395BD1/4505 (Model C - I believe)

System Soft: 05462AD1/4605

Amplifier: 00017600/3105

CD Changer: C38/3003

If it matters, the car includes the Bose Surround System as well. While I have spent the better part of a month researching on RennTech for most of the information I needed, I would appreciate any clarification one can provide on these outstanding questions I have, thanks in advance to anyone who can assist.

I recently acquired a 2006 C2S with the factory nav. I have to say that it is torture to use it. The $200 NuviI bought for my other car is dramatically better! The C2S unit isn't a touch screen, so you have to use the knob to select letters: rotate until the letter is selected, then push, rotate again, push again, rotate past all of the letters to the menu item that allows you to input the text you just selected. I didn't spend the couple of hundred to update the database, so some streets are not recognized. Yes, it is nice to avoid the wires and mounting hassle of a 3rd party unit, but how about this: use a nice mounting bracket to avoid the suction cup nonsense, and have the Garmin or whatever hardwired through the glovebox? You'll save alot of dough, and have a a unit you will be happy to use. spend the money on a bluetooth/ipod retrofit unit from bumperplugs.com.

I can't comment on the aftermarket head units. Some folks on the forums don't want to mess with anything that isn't stock, that can't easily be undone.

Good luck!

My brother has the Nav in his car. He cannot

work all the knobs. He mainly uses it for a display

that he can zoom in or out.

I tried using it but it does take a learning curve to

figure out. I would not recommend it to someone

who does not know haw to program a VCR.

I purchased a 2005 C2 equipped as your 07 is. I had the OEM nav added at the dealer. The lack of a touch screen has not been a problem for me, the system does not seem slow compared to other vehicles I have driven with integral nav. Like any new system, at first it took some getting use to. I like the built in, as opposed to the "stuck on". In my previous 911's, I had the talking Garmin, but never again. The Porsche folks are slow to change, but I contend ity is because they seek to do the best job for the car. As you can tell I am partial.

Just one person's view.
