This may help.....http://www.corvetteactioncenter.com/forums/c5- technical-and-performance/112952-battery-replacement- procedure.html
I have disconnected my 2002 Corvette Convertible battery many tines and never effected the radio, even the station selections are still there. I do have problems with different things like ABS, Column Lock etc. giving codes after the battery is reconnected saying they need to be serviced but never the radio.
