[mkgmap-dev] Unable to send maps with MapSource

I have tried to send maps generated with --index (r1293) to the card in my nuvi, but after some 25% of the process MapSource (6.13.7 and 6.15.6) always ends with an error with a report like this: App: MapSource AT: ... OS: Windows XP Service Pack 3 Processor: ... MDR_TRIM_ADDR-CXX-321-6.13.7.0 or MDR_TRIM_ADDR-CXX-346-6.15.6.0 I also tried with the card directly inserted in the computer, not in the nuvi, but the result was the same. May it be due to some error in the map or isn't it possible to send the maps to cards? Regards Carlos
