Top 20 Pioneer DEH-P7900BT CD Player Questions & Answers

Possibly shorted unit. But sounds more like it reset all settings to 0. check ground on head unit itself.

The flashing blue light notes connection attempt to a bluetooth device.

You are not going to be able to get the stock changer to work with the Pioneer deck. They are not compatible.

I say it is the screen or face if you well mine did the same thing and it is cheaper to find one on ebay than to repair it. I checked one place out and they wanted like 60.00 well good luck and take care

If your head unit is installed correctly there is a 10 amp fuse on the yellow/black lead. There may also be fuses on the solid yellow lead, and the red lead.

select the station you want then hold down either the select button or the 1,2 , 3 button for a few seconds on each one it will set it for you

Check the inline fuse on the yellow/black lead, the solid yellow lead, or the red lead.

Esto no es una solucion, pero la misma cosa esta pasando a mi. Estava trabajando, pero en un momentito se cebro.

pienso que tu radio no cirva. La misma cosa esta pasando a otros dos personas en estos forums.

my espanol es muy mal.

on your wiring harness behind the stereo, you should have 2 blue wires. one solid, and a second blue wire with a white line on it. the one with the white line is your remote turn on. the other one is for a power antenna, and wont work to keep your amp on.

I would check both of the power wires for the unit. There is a yellow one and a red one. The yellow one always has power regardless of the position of the ignition switch. The red one only gets power when the ignition switch is in the on position. Also does this only happen when the vehicle is in motion or does it happen just sitting and listening to the stereo? It also could possibly be the ground wire not getting a good connection. Make sure the ground wire is tightly connected to something that is metal. Good luck.

This sounds like a wiring problem. Double check all of you connections. If the Connections look good then I would check the connections inside the radio. Check the power wire mostly. The wire could have a bad solder joint inside the radio itself.
