well my z2 needs to be sent in for repairs. average cost is 230$, really debating to just buy a new unit either the 8400bh or avic-140bh. I really like the 8400 much better, the 140 screen shots look really plain. the 8400 has a much nicer appeal. the only differences that Im seeing is the Nav. Hd .(Nav I can always add on) what would you do, and why. all input is appreciated
thx!!
