genesis v8 18

Do you lose your phone and address settings after disconnecting the battery?

Does anyone know where to go to get the emblems for the V8 with 18" wheels? A while back, I checked online (Ebay) and found a couple of vendors, but unfortunately, did not buy. Today when I went on, only one vendor has the emblems, priced at over 3 the price I'd seen before. Does anyone know...
