Now to my real motivation for this review:
Unfortunately, my first unit had approximately 6 weeks a defect - sporadic loss of satellite reception. On Monday I received (by phone) from Garmin support an RMA number for returning the product. On Tuesday morning, my input has been confirmed, and on Wednesday I was able to unpack a new device from the original box !! Could not be better.
Now I am looking forward to the next biking and hiking; Incidentally, the free OSM maps are truly outstanding.
