Ok so I replaced the radio in my GF 07 Matrix with one from an 08 Yaris that has MP3. The radio fit right in with just the swapping of brackets, the connectors are all exactly the same and it overall works. The only problem I noticed was at night when the lights came on the radio display went black. After a few minutes of playing I noticed that the lower I turned the dimmer switch the radio got brighter. Does anybody have any ideas of what to do with this? at worse case I either disconnect the light wire or try to come up with a relay and a fixed voltage but would have to figure out which wire and what kinda of voltage it would take to dim it slightly when the lights come on.
