Same seller was doing same deal when I bought my Garmin Zumo 395 LM, I saved $189.90 which was the cost of the tyre sensors, I also found that they carry all spares for them like when I wrote of the Rocket, somehow the GPS received only a minor mark on one corner whilst everything else in that area was crushed including the power cable for the GPS, surprisingly enough ( the power cable is part of the hardwiring kit and cradle, I was horse they would make me buy a whole new cradle but that was not the case) I was able to order just the power cable for $30 including postage and had it within a week and that a,so proved to me the toughness of the Garim product as it is still working perfectly on the Explorer
