- "You state “Try unmark the Navteq from the insert page / signatures “, this is not possible since the Nuvi 765T with USA/Canada does not have that option to select different carriers."
You can manually choose a provider, setting the frequency in the GTM Status. Press Reset in FM Table and press Norm (normalize) to scan again and then set the frequency by pressing Mark in the GTM Status.[/QUOTE]

Thanks for all your suggestions, there is no option on a 765T to "press Mark in the GTM Status".
