8.4 map update info
Currently have a working 8.4 head unit with navigation in my 2013 my14 gc.
Have got a hold of another 8.4 unit out of a 2017 with navigation.
Thinking of doing Mousie”s update if maps on the spare 2017 unit.
Questions- will the 2017 unit work in the car?
- if i buy a SD card with igo maps on it, will the files on it be able to.be migrated across to the updated unit as per Mousies file instructions.
For you learned people out there!!
