Subaru TomTom NAV


Just got 2018 Legacy with 8" NAV that uses TomTom.

Anyone have experience with Subaru NAV?
I came to intersection of 2 state hwys and NAV rebooted. Trip route continued but curious if that tells me "something", like the ontersection doesnt match my map, etc. I checked via wifi and system showed 'map up to date'.

Copy GARMIN Favorites to Subaru GPS?

I have hundreds of saved places on my Garmins.. can I import/copy to NAV system?
