Summary: EDIT: This a cut & paste of my review (March 30, 2011) of the product when I bought it (refurbished). The old links died. My Maestro 4000 was getting old (being a cab driver, I wanted something new), and wanted a new GPS unit.
Summary: I purchased the 4370 from Circuit City on sale. The unit consistently overheats and shut downs during long trips. I would suspect from opening unit up that adequate heat dissipation was not designed into the unit. DO NOT BUY.
Summary: I recieved the 4370 GPS on June 26th, 2009. Bottom line is, it's already back in the box, ready to be shipped back. What a disappiontment this thing turned out to be. I purchased it for $275.46 on the 23rd and now I see Amazon has raised the price to $375.46 with a supposed retail value of $599.99?
Summary: I have owned a Maestro 3225 (Costco special) for 1.5 years. I recently purchased both a Magellan Maestro 4350 & 4370. I paid about thirty bucks more (including shipping/taxes) for the 4350 (3 weeks prior) but surprisingly I think it is worth more.
Summary: I was given this GPS as a gift by my husband. He bought a refurbished model here on Amazon. I was skeptical about using a GPS but was a believer after a trip to New York City. Unfortunately, several months later the unit just locked up while I was driving. Luckily I had paper directions as back up.
Summary: I was happy with the physical product, but it is worthless now because the most current map is from 2009 and Magellan is not providing anything newer. I won't buy another Magellan product. Please note that "lifetime maps" means Magellan's idea of a 3 year lifetime for the device.
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.
Summary: Google for 'Magellan Maestro 4370 Skin'. You may be able to add lots of great functionality to the unit. I've had many GPSes. This is the best of them. It has many features, so many, that some of them are not even emphasized/mentioned/described in the manual. For example, 1. Auto-Zoom: I love it.
Summary: I will not sugarcoat my experience with Magellan, it has been awful. The units (I bought two), freeze unexpectedly, overheat routinely, and I've been trying to return them to Magellan. Tech support is in the Phillipines and is absolutely the worst I've ever experienced.
