My current stereo remote CMRC2-BSS lost the function to it's "volume down" button. Clarion no longer makes this 6-pin remote. I have found a CMRC1-BSS 6-pin remote, but it's a 3" hole (vs. a 2" hole) and requires power for the LCD...and I don't want to go through the process of drilling a larger hole and pulling a 12v fused power lead. Has anyone replaced their old clarion system and have one of these laying around? Any better ideas...besides spending the money? Clarion also doesn't make an a 6-8 pin adapter...go figure.
The switch under the membrane has likely reached it mechanical limit or corroded. I'd try https://gaugesaver.com/ and see if he can solder new switches onto the board. As long as the board isnt epoxy potted, might be easily repaired.
