Hi Guys,
I'm in Australia and have the avic HD3 (equiv to Avic Z2 in USA), had it for 3 months now,..yesterday it played up. It was 38celcius outside, when i switched the car on the avic didn't light up (nothing happened)

. I then took the bezel off and had a look behind, unplugged it from the factory harness, plugged it back in, then it fired up as usual. Today same thing happened again (however the outside temp was not hot- 24 celcius). Did the same thing again- unplugged and then plugged in again- works.
What could be the matter? I use the PAC C2R CHY interface. not using steering wheel interface . Could it be the PAC thing packing up?
