then a right and another left - to get me back onto the same road) and I
reported the map info to Garmin.

I got back a few very personal emails from a human - not some " Thank you
very much for informing us " message from a message server. I was asked for
specifics on my map version, unit version etc, then: Reply from Garmin Map
