alpines double dins are awesome. pioneer for the most part has small screens and i’m just not a big fan of them after owning a d3. eclipses new units look nice. but as with all car audio, new shit sucks.
if you get the good pioneer screens (not the d series) you will love them. A guy on AVic411.com sells Z3 harddrives for a great price so you can pick up a cheap Z1 or Z2 and easily upgrade it to a Z3 FTW!
i have a z2 in my truck and another one in a box awaiting time for me to get the parts for it (old display model) and put it in my wife’s jeep. I love them. The gps is nothinig like you would get with Garmin (a little hard to use) but it works pretty well.
OP, Check this out. No hard drive but has USB input. 7" screen, looks sickk! It already has Nav but your probably better off buying a unit that has nav built in that an add-on unit.
i believe both were add-ons. i did have it set up for bluetooth so im pretty sure that i have the module or whatever is needed for that. HD radio- i think is an add on you can buy separately.
i have the head unit, the storable/removable navigation unit, a jl audio sub, and an alpine amp. all things im willing to sell. let me know if you have any interest
