Currently running an eclipse cd7100.
Love it, however double din touch screens are the future and in the future I'm looking into buying one.
Things I need from a double din. Android compatible, 3 sets of preouts at least 4volt 5-8volt preferable, active hpf and lpf for speakers/subs. aux in rear or front doesn't matter. SQ is a must, I mean I have one of the better SQ HU's out there, would obviously need something comparable.
Oh and I'm old school, really could care less about bluetooth/satelite radio/hd radio. all those bells and whistles are for new age kids.
