I have a garmin 1300 GPS. I flashed it many times and it worked well. At the last time when I successfully flashed and used it well, I used a rgn (No.1) comprised with the boot.bin from nuvi13xxand14xxseries_GCDFile_540 and fw_all.bin and fw1_resources.bin from nuvi1495_CHN_v250. This time, I flashed it with another rgn (No.2) comprised with the boot.bin from nuvi13xxand14xxseries_GCDFile_570 and fw_all.bin and fw1_resources.bin from nuvi1495_CHN_v250. The flash succeeded and I can power on the GPS. But the GPS can not recogonize unlocked detailed maps. When I power on it, the screen showed nuvi 13xx, but before this time, it showed nuvi 1300.
I tried to flash it with the No.1 rgn again, but the GPS still showed nuvi 13xx and can't recogonize any detailed maps. It only can work with base world map but with obvious deviation.
Does anyone have any ideas on how to fix it? Thanks a lot!
