That may be true, but on my end its been pretty good. I have an 8 core 4gb ram unit on my 2011 CXL 2.0T with the HK 320watt system, it sound amazing. It's crisp, the sound is still dynamic the eq does a much better job of isolating where you want your tones to be. I couldn't be happier. It's responsive no lag, good touch feel. It integrates with the car well. Backup camera with radar warning and
dash cam. Just too much to name. Also capable of using the torque app with the blue tooth odb. The only issue is radio reception is not as strong around town, and the onstar button won't remap. Also the android is housed in the DVD unit. Everything is plug and play. Your not dealing with the amps at all.
