Hello! I'm trying to install a new aftermarket head-unit in my SLK230 (Sorry about the typo in the subject line). The stock stereo has the telephone controls and the Bose amplifier. I'm currently having an issue where I'm not getting power from the 12v Constant wire (red w/ green stripe), but I'm getting power from the ACC wire (pink). I'm sure they're on different fuses, I'm just not sure which ones. Any help anyone can give me would be greatly appreciated!

Take the corresponding fuses out,do you get voltage--yes or no------then you found the problem.
