Can't help on the Garmin, but just to give you a heartwarming story of how we mere nothings can still beat the corporate bastards at their own games....
About six years ago I bought the cheapest portable CD player on the market (£34.99, IMSC) and a 3 year warranty (£40, ISTR). I then used this for music on hold on the PBX, which means that it is running 365/24/7. It fails every 18 months, I take it back to Dixons, they give me a new unit and another three years' warranty.
Makes me feel better about every time a corporate screws me.
