Question about Magellan RoadMate 700 GPS Receiver

1 Answer

Won't turn on

I used my RoadMate last night, but this morning it wouldn't turn on. I always use the cradle and cigarette lighter charger in the car. I checked the outlet in my car, and everything there seems to be working fine. But the Roadmate is completely dead. I bought it three years ago, and updated the software last year. Anyone know what is going on?

Re: Won't turn on

One of the wires in your power cord could be broken. If you have the a/c adapter, see if you can power up with that. If you know someone else with a working Magellan, you could borrow his cord to test your unit.

If not, check the car adapter with a continuity tester. Put one tester probe on one of the side springs of the car plug and the other probe on the outside metal of the GPS plug. If that shows continuity, place one tester probe on the end tip of the car plug and the other inside the the GPS plug.

If either of those do not show continuity, first take apart the auto side of the cord. Check the fuse and the wire to contact solder joints. If they seem okay, carefully cut back the molded plastic from the GPS end and examine the wire to solder joints. If any are broken, replace the cord or resolder the joints.

Broken RoadMate 700

Here are a few tests you can do. Bear in mind if the unit has not been charged for some time and the internal battery is completely flat, you will need to leave the unit on charge for some time even to get a charge light from the LED. Leave it on charge for at least 2 hours. First, check the LED is lit when the cable is plugged in to the cigarette lighter socket and/or mains charger? If it is not, the fuse in the cigarette lighter adapter may be faulty or the charger may not be working. If the fthe LED is lit, then is power available at the end of the cable that connects to your unit? Use your DC voltmeter to check this. If no power is available here, then your cable/charger is faulty - obtain a new one. If there is power at the connector, then the unit may be faulty.

My location is stuck at last place visited. It got mailed then wont leave the last place.

Are you talking about the Last Position or Location..... The Last Position is where the GPS came off the cradle or holder... once you connect it to a cigarette lighter adapter and remove it, it retains the Last Position... to create the Last Position when plug into lighter, remove it from Holder /Cradle then turn off unit... this will create last position... to find it go to your Favorites it will guide you to your car

This feature is awesome if you park your car somewhere, you can always find it by going to your favorites ... last position

Garmin Nuvi 750 car cradle/charger does not charge the unit. USB charger works, so not the battery. Replaced the cigarette lighter jack and still does not work. Problem must be in the dash mount cradle...

Hi tbrick

if you dont have the original charger, the 750 take a special car charger because of the traffic has a flat end about 3/4" to 1" long that fits in the cradle, but you can use a garmin usb charger, you just wont be able to use the traffic feature.

if thats a little confusing ( i tend to do that) i try and explain it another way.

if you think you need or want one of those chargers, just post back to me.

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.

My garmin charges with my computer but stopped charging in the car

The most obvious answer is a possible blown fuse in the cigarette lighter socket or the in the tip of the charger plug. Most charger plug fuses are accessed by unscrewing the metal tip. Check both for good fuses.

If this doesn't solve the problem, make sure the points of contact between the charger, cradle and GPS are all free of dirt and grime. Don't forget to vacuum the cigarette lighter socket - especially if it is used as a lighter, too.

Charging unit with AC adapter

I have a 100v A/C power / charger unit for my garmin C340 GPS that I use to charge my Garmin's battery every day. I can use thj adapter to run the GPS, or just turn it off and let it charge the GPS. But it connects dirctly to the Garmin GPS unit, not to the cradle like the Cigarrette lighter unit does. .

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!
