I checked the wires at the loom plug, all look good. I fished out the aux connector as well, and plugged my Sirius into it. AUX works fine. So its the tuner... Next I rip out the whole mess, bring it in the house and test from the AC power supply....

Any advice on how to troubleshoot the tuner is most appreciated! I guess check the power line, LED etc first. After that Im clueless...
