Summary: The only "major" flaw is losing of all state roads when the unit is left on 24 hours a day, 7 days a week. At least one time a week the unit has to be reconnected to the computer via a USB cable in order to get all the non-state roads back. Once the non-state roads disappear, you will get an invalid address. It looks as if you are in a middle of a field. Powering off the unit and powering it back on will not work. In addition, unplugging the unit from the cigarette adapter which causes a power down, leaving it powered off for 30 minutes and powering back on still does not rectify the issue.
Majority of the times the maps are up to date. Not perfect, but I am sure a lot of GPS's are like that. Traveled to Fort Dix, NJ (for my first time) and it had me turn into a road to get on the base that has been closed for over 4 years. After getting on base, the address took me to the edge of the woods and instructed me the destination was on the right in 500 feet. The address was correct, however; the GPS Unit did not know where to go. (Maybe a government thing, but I do not think so).
A minor issue, when you decide to go straight instead of turning because of a known obstacle (road construction), the GPS Unit shows you as turning. This is no big deal as the unit assumes you are making a turn. This is really bad when you have to make a Left, then a right, followed by another left. Had this issue in Maryland when there was a new traffic pattern. After making a wrong turn, I was able to navigate back and get back on track. The unit was 100% inaccurate during this whole process. I believe it was due to maps being out of date.
When searching for a resteraunt, where there is no known name, for example, search for "Bobs Place". After searching for about 3 minutes, the unit just shuts off and reboots. This happens all the time.
If using just the navigation without providing a destination address the GPS Unit is extremely accurate, within meters of your actual location.
Magellan provides online software updates and map updates for this unit. I initially had a problem getting the Map Updates for this unit, but they changed their software to allow this unit to receive updates. I kinda wonder if I got a bad unit with the issues I have been experiencing.
Although I have had some bad experiences, I would definitely recommend this unit. It is great and you can work around these issues, although the money that is spent, you should not have these problems.
Only suggestion, I wish it had a blue tooth interface that I could send a destination address to the GPS Unit from my iPhone and have it use my currently location as the starting address. This is great for emergency response vehicles.
