receive the 1700-lm a day later than the estimate delivery date . delay be due to UPS send to wrong facility . I unpackage the 1700-lm and read the manual . the manual state a fully charge battery would last about 30 minute and that the battery in the unit do not charge via the usb connector ! go to you car and charge the Magellan for a few minute . I charge it for 15 minute . I then install the Magellan Content Manager , register the gp , and proceed to do the software and map update . that process take about 1.5 hour , so patience be a must . I have my finger cross the entire time . I notice that the display be dim while connected via usb . it update successfully , I think because the battery have a good charge and the display dim while on usb . I take the gp to my van and mount it use the provide plastic base , connect the power , and start it up . it take less than 15 seconds and the unit acquire the satellite signal . I fiddle around with it and decide I like it . one feature I like be the pous search . I enter a pous and it could not be find . a message pop up and ask if it should search nearby . after about 30 seconds my pous appear . one issue I have be with the piece of the mount bracket that connect to the back of the gp . it do not have enough articulation for my liking . I can not position the gp to the exact position I want . my view of the screen be usable but not exactly where I would prefer it to be . the screen display be between 7 and 9 . the volume adjustment be a 10 . screen sensitivity be between 8 and 10 . re-routing time be between 7 and 9 . a feature from other gp 's I have own that I wish the Magellan have be a trip computer . I also wish a ac power adapter have be include . now I have to go out and buy one . if one have be include I would not have worry about the gp shut down while update . overall I recommend the Magellan 1700-lm .
