When replacing vanity-light bulbs, don't...
 

Change the bulbs with the assembly still in the headliner.

Lost one of those buggers up there and couldn't find it. Pull the cover off, then there is a tab to push to bring the assembly out of the headliner. Then change the bulb...

I'll have my stereo guy dig it out when he is doing the mirror power attachment for the V1.

Where are you located? Where is the stereo guys shop?
Would like to get my V1 installed as well.

I am in the Bay area - probably going to have Bing over at Simplicity in Sound do it while he is upgrading the subwoofer. Not sure he would take on a small-time V1 project by itself.
