Summary: The Magellan Maestro 4370 may a good product for some. Mine on the other hand has turned out to be a lemon. As in my overall rating shows, The display is great, Features are exceptional, But the performance lacks a lot. Without warning the unit freezes up until it automatically does a hard re-boot,(Wiping out all saved data) Or the complete depletion of battery power and a hard re-boot.
Summary: The Magellan Maestro 4370 I purchased on eBay from seller ZKARLO (164967) has some serious problems. The unit will only operate when plugged into the car charger and no matter how long it's left on charge the battery will not accept a charge (Shows only two bars on the battery meter). The supplied USB cable, GPS to PC, did not fit the 4370. It seemed to be the wrong size at the 4370 end. It was a Mini-A and should have been a Micro-B.
Summary: Beware of the Magellan 4370. In a year and 1 month, I went through 4 of these units before Magellan gave up and sent me a different model of GPS. The first two I received, the battery would not hold a charge. The third unit, hung up multiple times per trip usage. You have to power the unit off/on to reset or at other times, you have to press the reset button on the base of the unit, to get it to reset.
Summary: This unit is absolutely top rate when locating you and getting you dead on to a requested location. However, with the unit less than a year old, the battery has completely failed. This means that if your cigarette lighter turns power off when you turn off the ignition, then the unit has to do a total and complete reboot, which sometimes takes 10 or 15 minutes. The battery cannot be replaced, but you have to do an RMA and send the unit back to Magellan to get it replaced.
Summary: Update 10/08/09 - they have a firmware upgrade to the unit that helps some of these things and adds a couple of features - still hangs up about once a week - aggravating. I raise it from a one to a two - still not very good, but an improvement. Compared to the old Sreet Pilot I had, this thing is not worth the powder to blow it to (your least favorite place here) First a few Positive things: 1. Great display - resolution is good, even the 3D buildings are good. 2.
