Can I delete all the unnecessary files and folders in the internal memory of my nuvi 2797LM that I don't need or want? It's loaded with all those language files that I will never use. I guess a better question is can you tell me which files I don't really need, and then can I delete those files. There's vehicle files, language files, and who knows what else.
Likewise can I also delete unnecessary files and folders on the micro SD card?
I'm hoping I can gain enough space to load the latest CN North America NT base map. As it is it won't update from Garmin Express.
So what's my choices?
