excuse my newly discovered ignorance, but I thought the PCM (3/3.1) on all 997.2 turbos (as well as 09' 997.1) had Bluetooth, ipod connectivity and Sirius/xm radio? this is relevant as i'm in the market for a 997.2 TT and is important to me. any explanation will be appreciated. sorry OP, don't mean to hijack your post
True- but no BT audio streaming, and the GPS isn't the greatest. Honestly, if it had BT audio streaming, I would live with the GPS.

Yeah, the Bluetooth and lack of HD Radio are the worse. We have some great secondary HD radio stations in Northern California. Also, been spoiled with backup sensors and cameras for too long.

I can't imagine why someone would pass on a car wth an aftermarket PCM. The install kits are plug and play so there is no wire hacking. If you change speakers and amps that can all be restored without issue as we'll.
I recently changed out my factory PCM for a kenwood (ddx991hd) I love it. Much better interface. Good Bluetooth for phone and audio. Back up camera and front camera are going in soon.
I kept the factory PCM so when I sell if someone really wants this unit back in I can do so with ease.
I guess this debate is similar to those worries about an ecu flash or modified exhaust etc. Not all mods will be for everyone. Do what makes YOU happy while you own the car. Worry about resale when the time comes. I highly doubt you'll have a hard time selling Down the road

Though the only next, best thing I can see ever owning is a $200K 991 TTS.

One word though. Adding an aftermarket head will lead to many error messages in the computer when you go to the dealer. They are all related to a lack of communications between the pcm and various units on the car such as the steering column. These can be removed but they come back right away.
No big deal but if you bring it in for service, let the mechanic know so he doesn't suspect there's a problem somewhere.

bump, I'd like to get an answer to this from someone
i've been in OPs shoes many times. double dins are very nice but over time the non oem look starts to boher me. i dont know what it is, it just does. also a lot of aftermarket audio system introduce electrical issues down the line.

Has worked great for me in many vehicles to add streaming capability.

I know, I know, I am just super lazy and love the ease of the backup camera.

To the op's question:
The OEM PCM units in these cars were dated when they left the factory - so glad I swapped mine out.
It is easy to go back to stock if you want, just keep your PCM and spend an hour or two at most removing the aftermarket head unit and NAV TV module.
