Query: Unit shipped with wrong mounting bracket

Although the 4040 itself is a very nice GPS, Megellan packaged the wrong mounting bracket with the unit, this means you can't use it in the car. Amazon was nice enough to replace the first one via overnight shipping but the replacement unit had the same bad bracket. Called Megellan, first they promised to send the correct part overnight - did not come. Then they said it was on backorder and had no idea when it would be availible. I can't recommed anyone buy this unit until Megellan recalls the bad units and starts shipping good ones.
