Question about Magellan RoadMate 800 GPS Receiver

Magellan Roadmate 800 - External Power Connection

When I plug in a power cord (electric or cigarette lighter), the power indicator light will flicker with movement of the unit or vibration when in a vehicle. I obviously have a loose connection inside the unit. The GPS is no longer under warranty. How easy is it to open up the unit to check / resolder the wires to the external power connector (especially considering it is impossible to get a service manual. The reason I am posting here, is that I do not trust Magellan support/service because of the stupid answer I got to a simple question like "How do I get a unit repaired when it is no longer under warranty?" - and - "Do you have any authorized service centers or must I send the unit to Magellan?". Their answer was "buy a new cigarette lighter adapter and/or power cord".

Re: Magellan Roadmate 800 - External Power Connection

The only thing I can think to add is a general question to Magellan asking why they let a four-year-old child design the power connector as "lightly" soldered to the main circuit board. Very dumb...

Re: Magellan Roadmate 800 - External Power Connection

Most of these model 800 units seem to have the same problem. THe next thing to happen will be that the center(positive) pole in the unit will eventually break off completely. Take a look at the "as-is Roadmate 800's on ebay. Most of them have broken power plugs as well. I was quoted $49.84+$6 shipping to repair it. Good luck.

My Magellan Roadmate doesn't work anymore when I plug it into my cigarette lighter. It says the battery is low and it is shutting down. The unit did not come with a battery charger so I am confused about...

there could be a few reasons why this is happening....

there should be a light on the car charger that comes on when you plug it in, if it isnt on when not plugged in to the gps, but while plugged in to the lighter...either the lighter fuse is blown, or the charger is defective.

if the light is on, on the charger and it still wont stay powered on, it probably has a bad usb port (very common on this model) but it could also mean the charger (if not factory) is not compaible with the unit.

another way you can try and charge it (if you determine the chargers at fault) is to hook it up to your computer via the usb cord that should of been supplied with your unit.

HERE is your will show you the differant charging options..there is also updates on that page if you need them

let me know if you need more help.

Magellan RoadMate 3000T. When plugged into the cigarette lighter, I only get a little red light in the upper right corner. How do I turn it on? I can't understand their symbols. (it is a hand me down from...

Download the manual from here.

The LED in the upper right corner seems to be a charging indicator, so this means that the power supply via the cigarette lighter seems to be ok.

To switch it on, press and hold the power button for 3 or 10 seconds (depends on the state of the device - whether in sleep mode or off).

I have found my friend who is very familiar in electionic and small appliances to help me. I can fix it too, but unfortunately I do not have any soldering tools and parts here. I will bring it to Hong Kong and let my friend to fix it. It's very cheap if we find anyone to fix it in China where Magellan is assembled . Thanks.

Brand new Magellan Maestro 4000 does not turn on or indicate powe

I had the same problem and I solved it by cutting a few strands of speaker wire and twisting them together and inserting them into the center of the generic car gharger end which plugs into the Maestro 4000, It seems that the 4000 has a very small center conducter on the GPS itself and by adding a few strands of speaker wire about 1/2" long into the plug before pluging it into the 4000 it allows it to makes contact with the small power inlet conductor which is smaller than most generic cigarette lighter 5vdc power cords. I did this to mine and it powered up right away. The other solution is to buy the actual car power cord from Magellan which has the proper size connecton and makes proper connection all the time.

Magellan roadmate 2000 no power

the following advice pertains to the following magellan gps systems.

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

Hello kdiltzbook,

Most GPS units can be charged three different ways:

1. Connection to a computer via USB port
2. Connection to a automobile via cigarette lighter plug
3. Connection to a wall outlet via an AC adapter

Typically most GPS devices these days include only the USB cord. Some GPS units also include the cigarette lighter plug. For most GPS units the cigarette lighter plug and AC adapter are optional accessories have to be purchased in addition to the GPS.

You don't mention which model of Magellan GPS you have so I am not sure which cords your GPS should have included. It sounds like you have the cigarette lighter cord and the USB cord? I am sure that Magellan has an AC adapter available for your GPS. You will want to contact them directly (their website is or visit an electronics store that sells Magellan GPS receivers (such as Best Buy™) to purchase the adapter.

However, most GPS receivers can be charged from the USB programming cord on the computer. However, ensure you are plugging the cord directly into a USB 2.0 on the computer itself NOT a port on a USB hub. (A USB hub may not output enough power to actually power and charge the GPS.)

You will also want to check and replace the fuse on the automobile plug.

I believe that both the USB and automobile cords should be charging the GPS. If neither adapter is charging the unit then the problem may be the GPS unit itself. The GPS may have a bad battery or problem with its charge circuitry. If that’s the case the unit may require factory service as the battery pack is generally not considered to be end user replaceable.

No power to unit, but powers on okay in house with AC power adapter

Not sure if you'll see this post, as you asked the question back in Nov, but I
thought I'd tell you what I know anyway.

I and my parents bought the same exact unit within a week of each other.
There's works, and mine does not.

I took their cradle, and hooked it to my GPS, and it came on, no problem.
I took my cradle, and hooked it to theirs, and boom, nothing.

So, with that, I was able to isolate that the problem is definitely in the cradle.

I went to the manufacturer website, registered my Magellan Roadmate 700,
and then I was able to contact customer support. I am writing to you as
I wait for their reply. Here's their website.

Hope this helps!

Magellan Roadmate 700 does not power on

Hello, Rafster! Cigarette lighter plug problems are not uncommon, and - hopefully - this is the source of your problem. Because the green LED on your plug is lit, it would suggest that the FUSE inside is okay. Still, it's worth checking! The plug is easy to open, and the fuse easy to inspect/replace. IF the fuse is okay, the cord itself or the plug end that attaches to your Roadmate could be damaged. In order to determine this, you would have to check for voltage at the output end. But, you'd need a circuit tester and a wee bit of electronics knowledge to test it. If you don't have access to a tester, then the easiest test is to simply purchase a NEW cigarette lighter cord. You can get them at most retail discount stores (BestBuy; Circuit City; WalMart; etc.); RadioShack; or directly from Magellan. They're generally less than $10.00!

Lost power- will not come back on

If you have a multimeter you should be able to check the out voltage on the powersupply to make sure the power cable isn't at fault. You may also try wigling the power cord a little bit to see if the unit will then get power. If so you have a faulty powercord. If there are any fuses they should usually be accessible from the outside; that's the point with them - they should be easy to change. I would put my money on the power cable. If you have access to a diferent power source try that out. If the unit works with a different power source your power source is at fault. If it still doesn't work the problem is within your unit. Check to see if any pins on the power source and/or the units power plug might be bent or dirty.
