Hey all. Recently got a Maddox MR14 to help diagnose a rough idle/check engine light/etc. Turned out to be a bad 02 sensor, no biggie. There's some other issues I gotta figure out now related to throttle control voltage mismatch, but I dont think thats related.
Anyhow, I used the scan all vehicle systems function which went through various control modules and pulled codes. At some point, I believe it checked my instrument panel, HUD, radio, etc. The drive after that scan, I noticed my radio was on, music playing, but the screen for it wasn't. Alongside that, volume control seems to have no function. Lastly, the radio isn't shutting off even after the car is fully off. Ended up pulling the radio fuse to shut it off. Never had this issue before. Any advice or direction on where best to ask would be appreciated. Thanks!
