OSM exported Map with Garmin Street Pilot on iOS iPhone or iPod

Hey Guys,

I have tried installing a map exported from garmin.openstreetmap.nl for use with Garmin Street Pilot on my iPOd 4G (using bluetooth GPS), I installed the map as detailed in this thread. My device is jailbroken, but I have a licensed copy of Street Pilot. The same map works on my NUVI 260W flawlessly, but on the iPod it crashes 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? Are there any Garmin experts out there who know what the difference in the img file structures are, between what Nuvi is using and what Street Pilot requires?

AFAIA the garmin.openstreetmap.nl site exports the file in the NT format, and the Street Pilot app runs the NA NT format map that it came with just fine.

TIA,

Jon
