Bought this model as it had lifetime maps included, which my previous unit did not have. Too expensive to update the older model ($100). It starts immediately and I like the traffic conditions update. Warns you of likely mobile speed camera locations as well. No bluetooth in this model, but never used this option in my previous unit. Much, much lighter in weight, no battery backup. Easy and quick to update and I have been notified when this is available. Only had Garmin units and have been pleased with this GPS. Accurate, with photo display at larger junctions.
