well, i've gotten depenent upon the nav systems now - first it was the D1 in the denali - then it was the upgraded Z2 that replaced it, and was also installed in the M3 - the 968 was lacking a system, and none of the systems i wanted would fit - i insisted on being able to play a CD at the same time i was running active nav - the D3 didn't do that, and neither did any other units, without it having to flip outward, which hit the shifter
i also did not want to give up the audio quality of the pioneer premiere 980BT
i tried a garmin unit - cute, but could not hear it over the car and road noise - also no clean way to install it into the car's system - i wasn't fond of it in the windshield either
it took a while, and it wasn't cheap, but i think i nailed it
i found a now discontinued unit - the JVC KD-NXD505 - it is a single DIN unit with a 3.5" screen that has a 40gig hard drive, built in nav, yada yada, and with the additional blue tooth and ipod modules, will do everything i wanted - but, the audio controls were less than what i wanted, and certainly less than what i had
so.........back to shopping - i found the holy grail of equalizers - it's the rockford fosgate 3sixty2 - 31 bands of eq at each front channel, 27 at each rear, and 10 for the sub (i could do a center too) - built in crossovers, filters, time alignment, yada yada
that should satisfy even me
now i am looking to install the homelink mirror so i can finally get rid of the remotes in the car - then hardwire in the radar detector
