What's the verdict on PCM 2.1?
 

In general, what is the best way to go about updating your audio/nav/bluetooth? Adding Dension for added functionality or getting a completely new aftermarket head unit.

Dension seems to be a cheaper and much easier approach. I'm planning to add backup camera to the car in the not too distant future - would Dension in any way interfere with that?

Aftermarket heads - quick search shows that people here go for Alpine. Is this the only/best way to go about it? More importantly, I find PCM screen to be positioned way too low in central console and it is not very easy to look at when driving - I would really like to keep nav display in the dash; has anyone been able to do that with an aftermarket head?

P.S. Car in question is 08 Cayenne S.

Thanks!

The problem is that the accursed MOST/Bose system won't interface with an aftermarket head so you have to replace virtually everything; even the speakers, to do it right. I was quoted $2500-$3000 for Pioneer nav system by a shop that has done many Cayennes. Now know why relatively few here have posted info on upgrades.

You can buy a MOST-HUR adapter that allows you to use your existing amps and speakers with an aftermarket headunit. Most name brand systems also have adapters that allow your steering wheel controls to work. This is a nice option if you want to add things like: updated navigation with traffic re-routing, Pandora, iPod connectivity, etc.

If you want to spend less money and keep the factory look while adding a few features, then the Denison option isn't a bad way to go.

I have a year old pioneer. Although I really enjoy WHAT it does I almost HATE the way it does it. Its obviously 1000% better than stock along with sat/nav/tooth/cam however it's like an older windows type of experience. Someone should just make an iPad mini interface.

funny you would mention iPad mini. Back when I had Cayman and was browsing related forums - someone on Planet-9 did replace PCM with an iPad mini. Not sure if it was a Bose equipped car or not though. Obviously on that car you did not have to worry about steering wheel controls and I don't think there was a Nav display.

I've seen it done in a 996 also. While I think it's sort of a neat modification, I can't see it being that useful once you get over the novelty. I'd still prefer a proper double-DIN system with a proper nav system. But, that's just me...

The MOST-HUR adapter was the second option I was offered but it alone is $650. So for a decent aftermarket head with nav and the necessary bits like steering controls interface, dash surround, etc, plus the MOST-HUR, you're looking at a $1500 plus installation and you'd still be stuck with Bose mediocrity.

I replaced my PCM 2.1 in my TT with a Pioneer AVIC 140BH. It interfaces with my Bose amp and works great. I even had a back-up camera installed. Total was a bit expensive at +/- $2K.

That's pretty expensive.

However, if you really compare it to a proper system replacement (head unit, amps, speakers, etc.) then it's still cheaper. To get a total system replacement with good quality products would probably be double that price or more.

Did you use the MOST-HUR adapter?

What are the options for retaining the PCM 2.1, while replacing speakers and amps?

I don't know of any options for this. The PCM 2.1 system uses the MOST fiber optic ring to communicate with the amp. You may be able to replace the speakers, as they still utilize copper wires.

Hypothetically, your approach makes sense. Most people consider the OEM speakers to be the weakest link in the system.

Mine was $4800 from the dealer (previous owner) Head/speakers/sub/cam and install. Works like a dream and was a huge upgrade if you like your music.

I have the stock head unit that was dealer replaced 2 years ago. Is it worth anything to anyone here?
