    i have the same problem but my question is, does the magellan need to be on when charging or can you have the device turned off and charging?

No the device is not defective. magellan has this stupid usb interface problem preventing the unit from being charged and used at the same time, they do that so you have to use there charger. the unit will say usb connected and will not boot up like normal at all. unit will be locked up until the usb is unplugged. most usb devices charge at 5v with 500mA, and the magellan requires 5v 1A. Ipod Charger charges at the 1A with 5v but wont work

If sometimes it charges through USB and sometimes it doesn't, and you are using the *same* charger every time, then it sounds to me like the unit or charger may be defective, because whatever behavior you get, you should get every time.

It does not charge from a USB connection to a computer. When you hook it to the computer, it goes into its computer-docking mode, where it can't be operated, but you can access it and update its software from your PC (using the Magellan Content Manager program).

It does charge through its USB port from an AC adapter, as long as the adapter provides enough power (1 amp). If you're using some other AC-USB charger (i.e. from some other device), which does not provide enough power (say, 500 mA), the unit will not charge. It will sense that something has plugged into its USB port, but not seeing the needed power to charge, it assumes it's plugged into a computer, and puts up the computer docking screen. It is possible that this might be bad for the unit and/or the charger. And it is cerrtainly useless, as the unit is neither charging, nor capable of being operated.

And of course, it also charges through the car charger.

Once I updated my Magellan Maestro 4250 the beginning Magellan screen comes on & the bar at the bottom advances like its loading then it stops and freezes. I've tried reseting it without success...

Try re booting, turn off like normal, then when you go to turn it on, hold power button down all the way through the start up, and 15 seconds more than release the on button, now it's rebooted, see if that helps, let me know.

I updated my magellan 4250 to v4.86 and now it will not work with the car charger. Screen states that USB is connected and I should follow prompts on PC screen. It work fine before the upgrade.

turn it on and hook it back up to the computer and once it has installed, use the safely remove hardware wizard to remove the 4250 from your computer, then plug it into your car again...if that fails, turn it on then try the reset on the side (little pin hole) use a paperc clip to reset it.

if you need further help, just reply to this post.

My magellan maestro just stop working it will not turn on

there may or may not be anything wrong with it, but id be surprised if there wasnt. this model is by far the worst magellan has ever put out, IMHO, it is plagued with problems right out of the box.

wont start,restarts,wont charge because of the faulty usb connector,freezes,white screen,problems with the digitizer, the screen become littered with dead pixels and on and on.

anyway, charge your 4250 good for a few hours via the usb cable to your computer, the press and hold the power button for up to ten seconds or until it starts, if that fails, let me know and ill give you something else to try.

good luck

Firmware Update 4.86 failed in mid-update. Maestro 4250 will not respond. Menu screen comes up but will not work.

try and run the firmware update again. make sure the its fully charged or plugged in. this usually works though sometimes it wont depending on what files are missing..they are other ways to fix this problem, but i recommend you call magellan to get it fixed. they will repair any of their gps that were rendered inoperable do to there updates.

you can go here to contact magellan support

No a practical solution, but at least you will get your device repair, after being on hold for 40 minutes I spoke to a very nice rep, unfortunately evethough she didn't admit it, it seems a software problem with the new 2008/2009 map update, in other words no way to fix it, you need to send it for repair, make sure you tell them to update the device with the new 2008/2009 Maps, if not you will have the same problem later on, Good Luck
