Ok so the NAV unit has arrived… YAHOOO!
Appears new (all stickers in the right place no scratches). Obviously first thing I tried to do was to bench test-it. So I connected the power and doesn’t turn on. The buttons lights turn ON for about 7-10 seconds and the fan in the back is spinning, but other than that nothing (no response to any button). After the 7-10 seconds the lights turn off and the fan too. I tried to connect the RIM (data wires + power) and tried to fire it up. The RIM does send power to the amp relays wire (I even connected a relay and it works) but it does that as long as it has power. The NAV unit behaves the same (with or without RIM). The ‘99 CD/TAPE/Radio behaves in a almost similar manner except that does not turns the lights on (expectable since the lights are hard wired not data bus controlled) and does not respond to any button (except CD eject, and pull the CD if inserted, plus displays 00:00 time 5 seconds after I press the DSP button). Now the ’99 HU suppose to have a VIN in the memory (since it was pulled from a car).

Anybody tried to bench test the NAV unit? Keep in mind the unit supposes to be brand new never installed in the car (thus blank VIN in the memory).
Anybody?
