Bush's fault?
changing your battery would leave no charge at all in the radio for 'memory' of the currently selected stations- it is not their fault.
But did they disconect your battery to do the work on your Auto?
Go out and disco your battery and see if your radio looses its settings again.
There oughta be a law!
I tried being real nice to one of em this past Tuesday morning, giving a cheery "Howya doin'!" and the guy just groaned without looking at me. I realize that someone in this line of work probably isn't cut out to be a Public Relations guru, but at least my taxes could fund a class for these folks to learn "How to Win Friends and Influence People" from the late, great Norman Vincent Peale.
Can you help the Other Harry?
Did they steal your Jesus fish, too?
Many times during the troubleshooting of a problem, the mechanic has to reset the computer in the vehicle, in order to clear all the trouble codes. To do this requires the battery to be disconnected, then re-connected after waiting long enough for the voltage to bleed off. This also has the effect of clearing the clock setting and the station memory on the radio. There is one 12 volt wire going to the radio that is always hot, i.e., connected straight to the battery, that powers the clock and memory. Another 12 volt connection goes through the accessory switch you operate with the car key. Is that clear? When I take my car for service, I'm not that particular about the settings, but you can always take a second to write the settings down, BEFORE you have trouble.Keep it in the glove compartment or your wallet.
