My new AVIC-N4 has the same menu button issue as the D3 had. Still much better than the N3 which I just dumped which did not work at all. Pio Tech Support told me the Ipod configuration was taken from the D3 but looks much better than the N3.
I also got the Bluetooth Connector but it doesn't like my Treo 755p or vice versa. about to get that one sorted out somehow.
