Are you sure you need a battery? these model magellan are known for there bad power ports. they can be repaired, i even sell the power port and repair them for people that are not able to do it themselves but i dont think i can give you any contact info because it against fixya can keep reading to see how to remove the back of your 4000 to gain access to your battery.

to change the battery you have to be careful taking them apart or youllBreak the power port(if its not already broken) and the head phone port right off the board And it will probably screw the board up. i had few were ppl tried to Take them apart and broke the tracers right off the board (now there junk) Anyway, after the screws are out, get yourself a very small flat screw(they make plastic tools for this) Driver (jeweler type) and starting from the side opposite the power port and Head phone port (start on the side the power BUTTON is on, starting at the bottom Slip it along the seam where the front and back of the case Meet, but don't force it down inside the 2 halfs, you want to just put the blade In far enough so it slides along the seam and that its separating the 2 just enough to unlock the tabs from Each other see the pics. There is 6 taps to break free..2 on the top, 2 on the bottom and 1 on each side....don't worry about the on on the port side. Just tip the back of the case upward and that side will come free on its own. When you but it back together, the port side goes in 1st. Tip the rear of the case up and slide it in under the ports and then lay the back down on to the front half and it will snap together. I bet I made that as clear as mub. I'm not much of an instructor as you might of guessed by now. I do sell the ports for 12.00 if you need one...use a tester to check the port to the board, because sometimes they look good but there not contacting the board right or the pin could also be broken. Those ports are very cheesy, even if you fix it, those factory ports are doomed to fail how to change battery on megellan 4000 maestro - show%5cimg_03261.jpg show%5cimg_0how to change battery on megellan 4000 maestro - show%5cimg_03283.jpgi show%5cimg_03283.jpg show%5cimg_03295.jpg Good Luck Lanny Bill Learn from your failures or you will fail to learn.

I have a Megellan Maestro 4000 unit With the Power insert broken off the mother board, is there anyplace I can send it to to be replaced?

hi dre14u2

ask the fellow in the link below that sells the power port for your 4000 just skip all the mumbojumbo in between

The following advice pertains to the following magellan gps systems.

Magellan 800, 860, 2000, 2200t, 2500, 3000, 3050, 3100, 3140, 4000, 4040, 4050, 5310 and 6000t

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 below

this is actually a very common problem with these magellan power ports...they are poor quality from the factory and always and i mean always fail..the new ports that you find on ebay are 100% better then the factory port.

if your able to replace that power port yourself, you can get one HERE, if not, ask the fellow that sells them for help.

due to some dubious "experts" on fixya, im not permitted to help you directly, but please follow the link above to get further help.

let me know if you need more help or info

Megellan Maestro 4210 gps slow to find current location

I recommend you to reset it . Resetting should solve this problem .

Here is how to reset your Maestro :

1:Locate the button marked "Reset" on the left, right or bottom of the unit.
2:Using a thin object, such as a paper clip, depress the button for two to three seconds. The unit should reset.
3:If the unit does not reset, immediately press the button again and hold it for up to 10 seconds.

I can't tell if my magellan maestro 4000 gps is charging.

this could be happening for a few reasons but the most common is that its probably not charging.

before checking anything else, plug your 4000 in to a known good charger, then press and hold the power button for up to ten seconds till it starts.

if that fails, its likely not charging

this is very common problem with this and many model magellans.

the following magellan 2000, 2200t, 2500, 3000, 3100, 3140, 4000, 4040, 4050 and the 6000 are known to have faulty dc connectors...if your magellan gps is not charging or will not power up, its most likely the dc power port...

you can get help to repaired it, here
or buy the port here

if you need further help, just let me know.

My maestro 4000 cuts off during normal operation

its possible the unit is running off the adapter and loses contact and shuts off. this is a common problem on these type of magellan gps. typically they need a new power port so the battery will charge up and the adapter wont lose contact.

Magellan maestro 4000, 4040, 4050 vs mio c220,c230,

Don't buy a Magellan. There is little to no support, and their web based support redirects to no where useful for upgrades. I'd sell you my 4040, but can't in good conscience sell it to anyone.
