Summary: I have only had the 4040 for about a month now, and I have been using it every time I drive just to get used to it. I've also taken it along for one business trip of about 500 miles each way in that time. So far, I'm very happy with it: It always bought me right to my destination, it recalculates routes very quickly, and is easy to use. I really like the POI feature for navigating around areas that I am not familiar with.
Summary: This was the first GPS unit I purchased. I thought with all of the online reviews I had read that had good comments (even though there were some with unfavorable remarks about Magellan customer service) & the AAA features this unit had this was the unit for me. For the first week this 4040 worked great.
Summary: The Maestro 4040 has poor mapping on the east coast. I'm not sure about other parts of the country. It gets me to the correct city, but I have to figure out how to find the correct street address on my own. It tells me to turn where there are no roads and has even told me to turn when I was driving over a bridge. I wasn't in a newly developed area either. The Nuvi 350 is just as bad. I have used a Magellan GPS on the west coast and it worked great.
Summary: I bought the Maestro 4040 because I had a great experience with a previous Magellan GPS product. The Maestro 4040 has the following major defects using software version 2.04 that came with the unit: 1. Calculates routes that are not possible because the streets don't intersect. 2. Tells you to turn onto streets that are not there. 3. On many occasions the voice directions are the exact opposite of the green line on the screen which gives you the route to follow. 4.
