Hey guys I could use some help with a 2005 Acura MDX. I have it all rigged to tow, brake system etc. PROBLEM: After towing it for a while the battery is dead or near dead. I contacted a dealer and was told that it was the "hands free" system that stays on and draws the battery down. I was told I had to disconnect it by removing the rear view mirror, overhead console then pull down the headliner and unplug it. I was on vacation and do not want to loose my blue tooth. I disconnected the battery each time which lost the memory for several things. I can not identify which fuse protects the hands free circuit. If I can find it I can install a switch to turn it off when towing and not have to put in security codes each time. I am hoping that someone has been able to identify the fuse. The dealer was not very helpful. Thanks Mel Parks, Colorado
