You bring up a good point. Not enough "experts" know the details of the products they sell/install. If you can't trust Crutchfield, who can you trust? (Then again, Crutchfield backs their stuff up pretty well, so even if things go wrong, you won't lose much. It doesn't help that the Lamdbas actually come with a LOT of different audio options, which are not always clearly differentiated. I've had relatively good luck installing aftermarket head units over the years (well, except that they've been stolen 3 times!) Unfortunately, with the Lambdas, I haven't seen a "perfect" solution. Aftermarket units seem to usually have more features but at the expense of either quality or integration of basic functions. I've heard good things about the Kenwood units (there's a bunch of info on the Enclave forum). Personally, I'd like to see an aftermarket unit with extra functionality (like Bluetooth streaming audio, better GPS, and rearview camera functionality when not in reverse) PLUS all the features of the factory unit (including USB interface, ability to send Google/Mapquest directions to the car from a PC, etc). Probably just being picky. Most functions I wouldn't use all that often, I just want them! (I currently use GPS about once every 2 weeks, but I do use streaming audio regularly).
