Summary: For the price I paid for this unit, I was very pleased. A quick download from the Magellan website and the unit was updated within 10 minutes of its arrival. Bluetooth feature, and voice recognition makes this a great accessory to any vehicle! Highly recommended. I used to have the 3100, and the 4050 is a great 'step-up' from that series. A wider screen and total hands-free operation is exceptional.
Summary: I purchased this to replace an older Garmin. The first thing I noticed is how much difference the wide screen makes. Compared to my older 3.5 inch screen, it is much easier to see. I mounted it between the front bucket seats so I ordered an external antenna because I didn't think it's position would allow it to get a clear view of the sky through the windshield. It works perfectly and so far I have not noticed anything negative to report.
Summary: This GPS has great features with Bluetooth capability as well. My first GPS system I purchased was a Magellan model number 3100, but the 4050 is a big stepup. I am very satified with this GPS system.
