I sent my 860 to get serviced today cause I put a cd in their with a thick *** label(bootleg) and it got stuck. My brother car is down(getting a/an engine swap) so he lent me his 7700mp until I get my 860 back and **** that sh*t is like night and day, its better then having no radio for 5 days but honestly I have to turn the 7700 all the way up to get any volume out of it compared to only turning it half way up on my 860 and that 3 band eq I can't deal with. It like going from a 500hp beast to a 130hp cavalier. That 860 will spoil you trust me im learning the hard way until I get mine back. The lack of volume, features, and functions is killing me...eeehh
