Invisicord which attached from the Val 1 to the rear view mirror power cord. In any event, while I never dismounted the mirror, I did move it around on its ball joint a lot toying and playing with my install of mirror mount, Val 1 and Inviscord. Any why not? Did the same to my 2001 Monte Carlo with NO problem. But lo and behold, the Vette uses a stupidly engineered cam lock system to attach the rear view mirror to the windshield. Then my problems started. My mirror started wiggling and would not hold its position. Just like others on this forum with the same problem even though they had no detector attached to the mirror. So I took it to the dealer who told me a) there are no replacement parts for the disc held by 3 torx screws or the spring pins. You can only get a new mirror. They also told me this would not be covered under warranty because I installed that mount on the mirror. The "corvette" tech told me nothing could be done to fix it. So I ordered a new mirror for $300.00 (list price $368.00!).

Anyways, I took both mirrors today to a local place near me which installs customs parts on pickups/vans etc. Its not a garage per se and they do not do mechanical work per se. They took pity on me (not to mention they liked my 2007). They took a look at my wiggly mirror. He took a #8 Torx tool and easily unscrewed the 3 torx screws. He took the disk out along with the three pins. The pins were all bent and he took a wrench and straightened them. He put it back together. I took it out to my vette and twisted it in and voila!! its like new again with no wiggles . As a bonus, he cut a piece of black racing stripe tape and shaped it to the size of that stupid PASSENGER AIR BAG ON OFF light, put it over it and voila, that mesage is gone! Monday, the new $300.00 mirror goes back to the dealer for my money back and a good talking to the service manager!

The bottom line is the C6 mirror can take only so much swiviling on its ball joint and then that pressure gets to the cam lock which then starts to loosen up as the pins go out of whack and/or the little bumps on the disk get ground down. That really sucks. But it is fixable. So if you have the C6 rear view mirror "wiggles" just take it apart and fix it as told above, before you buy a new mirror.

Oh, I read somwhere that if you unplug your mirror and dismount it, NEVER start the car until you at least re-plug the mirror back in. If you dont, you will loose all memory of your various modules and they will all have to be reprogrammed.

HD has the bits 2 for 2.37 and a multi bit torx jewler's type screwdriver for a little over 5. $11 and my mirror is rock solid and I have a new tool.

Easy 10 min job.
