BTW, there is another method to resolve corrupted map issue in Nuvi, that is by flashing to a firmware that has disabled the software from looking for IMG files when booting up. Anyway, you should try the above first before proceeding with the alternative.
Tried....still don't work.....can advise how to flashing the firmware? BTW, the GPS cannot hookup to PC.
