Any 2 DIN will fit, it's just a "modified" fit. There is a small amount of trimming to be done. Nothing major or structural. Might not even interfere with reinstalling the factory radio again.
If you plan on just using bluetooth, you could buy an amp with built-in bluetooth, wire it to the speakers, and bypass the factory unit altogether. For the longest time, I plugged my mp3 player directly into my crossovers input. didn't even have a head unit.
Kenwood's cheap Excelon units are about the best under $200. It's funny to say cheap and Excelon in the same sentence. Excelon used to be their top-of-the-line starting at $600 and going well over $1,000. Now, for $150 you get "Excelon" and all the goodies like bluetooth, eq, color change led, etc.
