The only issue that I have had with the Garmin Routes is to RV parks. Twice I have been sent to a location that had nothing to do with the actual location of the park. In both cases, I filed a bad address report with Garmin so that they could update it in their next map release.
So now I verify RV park addresses on their website before I enter it in the Garmin.
