Sounds like you have an internal short in the stereo. Or could be that the face of your stereo is worn out too. Get another radio.

The temperature sensor or the gauge itself may be faulty causing it to jump around. As for the radio it could be the head unit itself or the cable to the antenna may be loose or disconnected.

body control module may be bad.

My stereo system for my 2005 Altima Nissan stopped working and wouldn't eject the CD. The CD has been removed but the CD player doesn't work and want take CD'S. The radio continues to work.

Take out the radio. Remove the nickel. Reassemble and reinstall. Next time feed it krugerand.

I would look for a ground that is inadequate.
If any part of this is operating essentially without shielding due to a bad ground, then cell towers, a radio or TV station transmitter, CBs, land mobile radio, amateur radio - any of these can inject enough signal to drive modern electronics completely bananas.
The onboard electronics used for just about everything that is remotely controlled by switches generates a ton of digital garbage and can interfere with anything.

The kind of problem you are experiencing started when we stopped using vacuum tubes 50 years ago operating at high voltages and started using semiconductors that use much lower voltages.

A tech with a common multimeter should be able to locate the missing ground connection without too much trouble.
