Battery Question
I just replaced my battery with an Optima Yellow Top, I had ordered a Red Top but it didn't come in when the they said it would and they couldn't find one locally so they gave me a yellow top for the same price 
When they replaced the battery, I let them do it while I watched because of the core, they connected some type of code reader to the OBD II port so "it wouldn't lose any of the memory" but I noticed the hood light went out as soon as the battery was disconnected. My question is: Did that really do anything? My radio presets were still set so it seems that some power was still available to the radio.
Thanks,
Johnny

The radio has a non volatile memory, except for the clock.
If you did not have to reset the clock, it sounds like the memory saver worked. Other wise, you may have had to set the clock, re-index the windows, etc.

On this same theme, do the cigarette lighter plug-in style "memory saver" type devices work with the C6? I've used these in the past with OBD II based cars when doing engine conversions. Just curious...

Yes I did have to reset the clock, it was exactly 1 hour off, and re-index so I guess that means it didn't really do anything.

Most memory savers use a 9v battey plugged into the power outlet. This problem is that as soon as someone opens the door or the hood and the light(s) come on, the small 9v battery can not supply the required current, due to the load, so system voltage essentially goes to zero, so the memory settings ARE NOT saved.

you do believe in magic, how about your memory was sucked in to a "flash drive" and put back in when the new batery was installed, thats how I think a memory saver would work, ya think? no nevermind I take that back, LOL

Did you even read the original post? The module/code reader that was plugged into the OBDII port was about the size of a motorcycle/lawn mower battery. I didn't think it would work but I was curious about the presets on the radio, which was answered in a previous post.
