Hello I am trying to get a Retrosound One C radio to work in a 55'. The radio screen lights up when the car is started but doesnt display any numbers or text. I have a good ground and 12v constant going to the radio but my switched voltage is only 9.5V when tested at the radio and at the fuse...

Hello, New to the forum. I recently inherited a 55' Bel Air from my grandfather. Really enjoying the car and how it helps keep my memory of him alive.

I installed a new Sony radio in the glove box of my fully stock 235 57BelAire. All hooked up and ready to go: however the controls don't work: can't adjust time or volume, etc? Pulled the radio out sent back to Sony: New radio arrives, install: same problem? Installed radio directly to the fuse...
