Nav/Maps Help

[Virgobrown]

Evening All,

I recently bought an RDS315 Unit, and it came supplied with maps on SD card.

Anywho I'm looking at clearing the awful music on the SD, but it's not exactly clear which files are for the Nav/Maps...what should I be looking for?

Also what are my options for updating or evening upgrading?

Thanks

Are the maps not on the RNS315 itself?
Do you have a picture of the folder structure on the SD card?

Can't see anything at all on the SD, just songs....

With RNS315 the maps are copied from the SDCard to internal drive and the SDCard with maps themselfs is locked in a special way after first use. This means it (usually at least) cannot be read elsewhere.
