Pioneer AVH 1330 NEX -- HELP!
Please help if anyone knows! This &&^&^$^ radio does not work as it should. Everything is connected correctly. But only one left rear speaker works. After a reboot, the front ones work and the rear one turns off. Further, as soon as you touch something in the settings, the sound disappears again and one rear speaker plays again !! Moreover, half the menu items are not highlighted and cannot be used !! And yet - I wanted to update the firmware but this is not possible !! He writes that the file is unreadable, although he downloaded according to the instructions from the official site !! I tried a million options and there is no sense !! How to make it work fine ???????????
Is this a good question?

Hi @max_nyc ,
Has it ever worked OK and is now faulty or is this a new unit or installation?
When it does this, does the power on the unit stay on fully or waver about, e,g display dimming brightening etc?
Does it work OK with the engine running? If so and it doesn't work with the engine off, check your car battery.
Have you checked that the earth connection to the unit is a good earth.
You've probably done all this but just trying to eliminate some possibilities.
If it is no longer under warranty you may have to open it up and check for problems . It sounds more like power supply problems due to the varying nature of the symptoms. So check the area around the power section of the pcb in the unit first.
Pioneer does not provide circuit diagram (none that I can find anyway) so fault finding in the unit won't be easy.
