here's what i found out about BT (also listed in my other post re CDR-30):
no-one at the dealer or anywhere else knows about whether A2DP (stereo streaming) is possible on a CDR-30 equipped with BT. so unless someone here on this forum has tried it we should assume "probably not", as this is a more advanced BT capability.
as for BT availability, the CDR-30 in an 09 or later car can ship out as a base version, or as a base version with CD changer support, or as a base version with bluetooth support, or of course with both. so there are at least 4 variants / part numbers for the CDR-30. all 4 can be bought new from the dealer, refurbed from the dealer, or used on ebay/craigslist/forums as there is quite a bit of replacing going on out there from folks adding PCM or 3rd party nav systems etc.
a CDR-30 with bluetooth support will only work "in a car that's equipped with BT or phone support". once installed one has to call into porsche via a dealer to get unlock codes to have the BT capability inside the CDR-30 (it's not an external module or option on top of the CDR-30) turned on.
apparently a CDR-30 with BT support doesn't cost more to buy, you pay for it upon activation.
