Excellent customer support and a very comprehensive web site.
This is their new slimline design and as a result, the speaker is a little tinny sounding as compared to the thicker 4040 which I also own. It is still very clear and understandable, even in heavy, noisy traffic.
Sometimes voice commands have to be repeated to the GPS but this is a minor inconvenience. I did not buy this unit for the voice command capability.
The 6 million POIs is a definite plus. Just about anything you might need is in there.
Magellan also uses the best chip design for satellite tracking so you will never be without service. I can even get full satellite coverage with the unit inside my home. Right now, I am in my computer room and have 6 satellites showing on my 4250. If I was outside, I would have at least 11 satellites showing on the screen.
The variable mounting system options that came with this unit are second to none. I believe Magellan has the best mounting hardware of any manufacturer.
Over all, this is a great looking, excellent performing GPS and the 4.3 inch screen is great for over 40 eyes.
