I've bought a second hand SPS switch but it has another cars settings on it.
What I want to do is
1) Delete the previous cars settings
2) upload my cars settings to the device and store them in the device incase I loose the map at any point
I've no intension of changing the map settings at any point, although I will upload valet mode when I go on holiday
None of this seems to explained on revos website for some reason ?
