Hey Guys,
I hope someone can help. I have a Central American Map which I was using as a secondary map on my Nuvi 260 (was named as gmapsupp.img on the nuvi) which Ive now renamed to gmapprom.img and dropped in the Apps/USA/Garmin-nav.app/storage-usa/. System directory and I can see it in the application.

When I try to use the go to address function the app is shortlising the correct addresses from the map, but when I click on one to start the routing the app crashes.

Does anyone have any ideas where to start troubleshooting this?


TIA
