Virzn Posted December 10, 2010 Report Share Posted December 10, 2010 Hi, I connected all wires for the P5200BT according to the manual (12V+,Gnd.,ACC,Light,Remote,Brake) but the HU doesn't turn on. I also pushed the Reset button several times but the unit is just dead. So I disconnected everything again and used only the Yellow wire to the cars constant 12V+ / Black to the Ground wire of my car and Red to the ACC. Still dead, no noise, nothing. I measured the voltage at the pins from the unit and all got power as supposted to be. It also doesn't matter when I interconnect the ACC to the constant 12V+. So I figured the HU must be bad and returned it to the dealer and bought a new one that arrived today. So I made a quick test and connected it only with the 12V+, Gnd. and ACC and guess what - it's also dead Guys, do you have any idea what's the issue??? Do I do something wrong? I mean one unit can be bad but two in sequence?! Please Help!!! Cheers Virzn Quote Link to post Share on other sites

wooward Posted January 23, 2011 Report Share Posted January 23, 2011 Created a AVIC411 account just to say THANKS!!!! I tested everything before I ziptied all my cables and made it look neat and the unit worked. Right after I cleaned it all up and was about the slide the head unit in, no power Tore apart everything, tested voltages, continuity, even used a power supply to power the unit. Nothing... then read this and voila, it turns on again. 5 hours wasted so far, now to clean it all up again. At least I was able to save wasting another day. Thanks so much. I really mean it.
