Updating magellan maestro 4250
8/ Wala theres your battery it is taped in place so gental pressure will be needed to lift it out Unplug and replace rebuild is the reverse of stripdown.
Once you put it all back together you will need to charge it for at least 4 hours.
For free updates, you must create an account on the website of the company (
--Nuvi 660 -- and not upgrading it or maps until Garmin fixes long-standing bugs/problems, and get maps to where they are much more current, AND corrected on a more timely basis when advised of mistakes. I think that one either needs to spend LOTS of time thoroughly researching a LOT of models to find the best fit for you OR.......go for a good deal.
When unit is completely off, then turn on, but this time, when turn it on keep the on button fully depressed, do not let go regardless as the unit is turning on, and even when it is coming on going through its thing, keep on button depressed for 10 seconds after unit fires up.
Magellan 800, 860, 2000, 2200t, 2500, 3000, 3050, 3100, 3140, 4000, 4040, 4050, 53t i fix these and many other magellan gps daily so when considering my advice , please understand i do not google my solutions.
assuming your car charger is working (the little green light is on) and your magellan still wont start up after holding the power button while its plugged in for up to ten seconds and still does not start.belowthis is actually a very common problem with these magellan power ports..are poor quality from the factory and always and i mean always fail.new ports that you find on ebay are 100% better then the factory port.
Then it means you will need to seek further assistance from magellan, because the solution for the unit is to connect it to a computer, and since the computer is not reading it, then you need to get to a close by magellan center or you mail them on this link Hope this helped.
Plug it into your computer to see if it recognizes it. If it still has the white screen, press the reset button with a pen.
