Thread: "Cannot unlock maps" error after reboot on 3790T

Traffic subscriptions are enabled by a code you must insert in Nuvi by attaching it to your traffic antenna,
but before you must go on your MyGarmin page
To enable Traffic you must enter FM Traffic reciver id to get a code to enable it.
You can get also your maps .unl and .gma files on MyGarmin page

PS: run also webupdater to download latest FM Traffic provider database.xlm

Thanks again for everything guys!

Should be better you make a Nuvi backup now, remember to enable hidden files and folders and do it
