I installed the ACC/IG module & Roof Controller module. I noticed that the radio stays on after turning off the engine, so it appears the ACC/IG unit works. The Roof Controller- one touch system works when I use the interior roof toggle, but when I go to use the Key Fob to lock/close the roof & unlock/open the roof, it doesn't respond. I've replaced both units twice and still doesn't function with the key fob. Hmmm?
