I currently have the same issue iwht my N3. I move the hide-Away unit from underneath the passenger's seat to underneath the dash pocket (2004 Honda Accord). The radio was working fine, but suddently it would not turn on. I open the location where the hide-away unit is located in order to check for blown fuse. Everything is fine. However, the N3 turns-on and the screens pop out, but none of the buttons function and screen is blank. I un-plug the cable from hide-away and head unit, the perform a reset, and still nothing.
Any one has any suggestions?
