first off deleting map data is not the way to clear f5сs codes - it actually deletes the mapping data - hence the head unit now reports ffff as the f5с application number.

Correct way to remove all f5сs on EntryNav2 is to send clear swt: 31 01 F0 03 01

You need to get map data for your region on usb and put f5с on usb to re-install the entire data set.

oh and PS - if you are going to use OEM map f5с then you will need a map set that is within the limit of the f5с.
