Thanks again. I'm not getting any blinking red LED indications when I push any of the homelink buttons. According to the install instructions, the switched power source should be connected to the auto dim/compass input and that the always-on power source should be connected to the homelink. That way the auto dim & compass will not drain the battery when it is parked. I'll have to get my trust DVM out again and check my power connections at the end that plugs into the mirror tonight when i get home. Maybe I have a defective cable from Mazda. Anyway, I need to get this sorted out quickly before the 14 day return period expires!!
