hey guys, i have had an Avic-Z2 for the last 5 years....
i admit, i had quite a few problems with it, but i just accepted it. i didn't like the super slow input for destinations, how it ghosted out certain letters when typing things, and the super slow ipod interface.
on top of all that, the GPS stopped working a while ago. i bought a brand new antenna, hooked it up, reset the unit, and it still didn't work...
the motorized face plate is now super, super slow. i have to use my finger just and push it to make it move.
that being said, it's time for a new unit.
i have read SO
