TX2010V6

My 2010 has 66K miles on it. Last night I used the key fob to unlock the door to drive home from work like I always do. It was 47 degrees out with some light rain. I got in the car and closed the door. The instrument panel was still illuminated when I turned the key to start the engine (normal). There was no starter activity as the car immediately had a complete electrical power outage. The instrument panel went dark. Nothing I did had any effect. No interior lights whatsoever came on when I opened the door. I popped the hood and jiggled the battery cable connections since I didn't see any corrosion and I didn't see what else I could do. I opened the driver door and was thrilled to have the interior lighting back. I turned the key and the engine started right up like it always does. There were not any warnings or fault indications on the instrument panel. Loose battery cable perhaps? The problem with that theory is that all of my radio settings remained intact. I later tightened the battery cable on the negative terminal since I needed to know that I did something to prevent a reoccurrence. What could have caused the total electrical outage?

I did not want to give up the compass feature by removing the fuse so I covered up the rearward facing sensors as recommended by suew. That did the trick. Thank you for the help.

Thanks for the info. How are the crossovers secured so they don't rattle?

I have a 2010 SE with SYNC and the standard 6 speaker audio system. Since the head unit is so tightly coupled with the car I wrote off upgrading it but I would like to replace the stock speakers. In addition to (I assume) a 5 1/4" standard speaker each front door has a small grill for a tweeter. I would like to go with components but I don't know if there is room for a crossover or if installation in general would be a problem. Any advice is appreciated.

I have a 2010 SE with an auto-dimming rearview mirror. Is there a way to disable the auto-dimming feature? The darkened mirror combined with my window tint pretty much wipes out my view out of the back window at night.
