I have seen many set-ups on the 997 with non-OEM head units. As I mentioned above, Alpine F1 Status seems to be the head-unit of choice for the 911's at AI Design. They do a damn good job making all your equipment look factory standard. Then again, they also charge $125 an hour for labor. If you want a new head-unit in yours, I suggest you give them a ring (website posted above on my previous post). When I buy my 911, I'll probably bring it to them as I will with my 987. :-D
