It may seem a
bit lot trivial, but the first thing most people gripe about after getting their finely tuned ride back after from trip to the local wrench jockey (read: you) is that they have to re-program the radio. Be calm. The first thing you need to do is refrain from choking them on the spot. The next thing you need to do is find a code maintainer that will skirt the whole issue next time.
A code maintainer keeps all the user programmed selections in stasis while the battery is disconnected — which happens quite a bit around the Toolmonger shop. The procedure isn’t difficult. Just connect battery clips to a 12 volt battery and plug the cigarette plug into the vehicles cigarette socket before you disconnect the battery in the vehicle.
For about $20 it would be great to have around the shop if sans-battery maintenance is in your future> Just keep an extra battery with a bit of a charge lying around the shop — we’ve got one — and you’re good to go.
