9volt battery to keep memory
I was told today that before i disconnect the Battery I should get some kind of adapter with a 9 volt battery and it will keep the memory alive in the car while the battery is unhooked - Is this true or another one of those myths. I need to replace my battery tomorrow so if this is true it might just help keep at least the Radio channels all set.

I've replaced my battery and unhooked it several times with no ill effects. You MIGHT have to reset the clock and the radio stations, but so what? Not that big a deal - IMO.

I don't know for sure since I've never done it --- but the "forum" has said many times that you don't need to worry about losing memory if battery is disconnected for "short" period of time. I always assumed that short was an hour or so.
To be on safe side, you might want to get one of those 9V adapters that plugs into the lighter --- they really work; I've used them before on older vehicles that lost memory instantly when teh battery was disconnected. Radio Shack should carry them and they're cheap ------------

I think the only thing I had to reset when I changed my battery out was the theft lock code on the radio and the radio stations. Everything else came out OK.

Unhooked mine for 4-5 hours for a VaraRam install (not sure why the instructions said to do that.......or why I did it) and lost all memory and the key fob's have never worked since, no matter what I do. Picked up one of those things for less than 10 bucks....worth not worrying or the possible subsequent hassle.

I have one. I have not had occassion to use it since I got it though as I haven't unhooked the battery in a long time (hmm, means I haven't modded in too long). Anyway, I was thinking that it is a good way to preserve the number of drive cycles on the car instead of losing them when you disconnect the battery - important right before an emissions inspection, which I have this week.
