Thank you for that information. Which wires are you checking for power going to the radio?

Customer: replied 1 month ago.
Red for ignition and yellow for continous
Expert:  Amedee replied 1 month ago.

Do you have a base or the premium radio?

Customer: replied 1 month ago.
Had infinity originally but after market now
Expert:  Amedee replied 1 month ago.

The gray/red wire is the constant power to the radio.

The pink/yellow wire is the ignition "on" power to the radio.

Here is a wiring diagram.

Expert:  Amedee replied 1 month ago.

If there is no power on one or both of those wires and the fuses are good, I would suspect a bad integrated power distribution module.

Expert:  Amedee replied 1 month ago.

one thing you can try if the integrated power module is not sending out voltage to the radio is to do a battery reset procedure. Sometimes it locks up causing this sort of problem. Just disconnect the cables from the battery and hold/rub them together for about 5 minutes and see if that does the trick.

Good luck!
