You have to love the Letter Carrier and Garmin
My Garmin 2820 was acting up.
I called Garmin and got a RMA # giving them my USA ddress ( the Letter Carrier)
It was shipped out of Vancouver by Canada Post June 28th
Garmin replaced the unit and it has arrived back in Point Roberts
If you need to send a GPS back to Garmin never deal with the Quebec service centre. They quoted me 4 - weeks turnaround time
