i dont know about the audio system........ the only reason i ordered the 801a was because i wanted the moonroof and tailgate step. now i got this crappy sony nav and audio system to deal with. also mircosoft sucks. the voice commands work like crap. i get so frustrated with the stupid thing. not that apple is any better...... it seems that my phone only connects half the time, and i know its my phones connection. but hey, i got my moonroof and tailgate step...... along with a shitload of crap i dont need.
