Hi i've started several attempts to flash the new firmware to my Nuvi 550. Neither the original nuvi5xx_regionfileonly__430.gcd (via garmincure3) nor the self created RGN File (via updater) worked. Every time i tried to update the process starts with ereasing the old firmware and then it stops with a nonspeakig error message. After this failed attempt the nevi works fine with the old firmware. So nothing happened.

I hope that anybody could help me with my problem.

Thanks a lot.

Ben
