Summary: I don't like that you can't just type in the address as you know it, and THEN search the area to make sure. You must type in the street name first (not the number part of the address), and only the available letters are highlighted. When driving more than 30 (or so) miles per hour, the little alert (sounds like a ding) comes after you've already missed your turn. Very frustrating.
Summary: Got this for Christmas 2010, it got in a software loop and would not work about October 2011, called and they said it was out of warranty since it was Manufactured over a year ago. Fortunately Costco was able to get me a record of the purchase and so sent it in and got a refurbished unit (as good as new that I could see).
Summary: So much to tell, this is a shortened synopsis. This is my second GPS, so I compare it's operation to the previous units. I "tested" the 1445T for 6 months before purchasing map updates. Basically the unit worked*, then I made the mistake of paying for the Lifetime Map Upgrade Subscription. At the time the new maps were installed there was also a software update applied, I have no idea which could be the problem. Ever since then, it's been downhill.
Summary: Magellan GPS is "OK". It beats having nothing. I purchased their top end unit after having great success with Magellan GPS in my Hertz rentals. Don't know why exactly, but there is almost no similarity between the consumer and commercial lines. Navigation is a B+ on a generous day. Can't see the screen in the daylight. Charges for map updats are too expensive.
Summary: I bought a Magellan last year. Right before the warranty expired the map screen froze at a particular location. My brother had also bought the same model and the screen froze on him within the same month. I sent it to the company and they sent us a "new" Magellan gps. Two months later, the same problem occurred. Three Magellans with the same problem. I would have serious doubts about buying another Magellan.
