Question about Magellan RoadMate 700 GPS Receiver

Power adapter for Magellan 700 is broken

I took the cradle (what connects to the back of the Magellan RoadMate 700 unit) apart and there are 3 solder connections on J1 for the power plug, which is no longer there. Which one is positive and negative and also does anything connect up to the middle connector?

If you understand what I am trying to describe, the solder points are vertical below the USB connector. From the USB connector down:
Top -
Middle -
Bottom -

Thank you for your anticipated assistance, I really miss my GPS!!

    I am extremely broke and own a soldering iron and was just going to remove the adapter and solder directly to board. Thank you anyway.

Connector J1 is the power connector. The left post corresponds to the center lug. The middle post is the outer connection. The right post closest to the USB connection is just an anchor - no connection.

Cradle defective


This cradle/power problem was a major problem at launch 4 years back - i had 3 units before I got one that worked OK and that replacement was itself a factiry refurbished unit. Even now, sometimes the power lead is verys ensitive and the unit shuts down.

Magellan Support is absolutely useless (apart from 'John') they just don't respond to queries. I updated to latest maps and firmware 6 (actually shows ver 5.37) on the understanding that I would get Magellan Tools and could then load cameras. BUT it has been such a huge waste of time.

I am at last binning my Roadmate and getting a Tomtom Go 720T with Traffic and cameras preloaded. It auto updates each time you sit the unit in its cradle linked to PC/internet.

Wish I'd never wasted over £800 on Magellan 4 years ago.

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.

Check the pins on the cradle. I've noticed that sometimes, my pins will become misaligned (they become bent, or unevenly spaced). Also, make sure the unit is snapping completely on the clip. Sometimes, the clip doesn't "bounce back" after the unit is released, and a subsequent attempt to attach the unit to the cradle results in a faulty connection.

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!

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.

Road mate 700


The flash card hole is supposed to be empty - all you need should be on the hard disk BUT the first Roadmate 700 I purchased was empty i.e. no software loaded. The second failed due to bad power connection, the third worked but was factory refurbished! what a crass organisation Magellan is!!!

Try fiddling with the power connection that goes into the cradle that the unit sits on. The power connection is ultra sensitive. BUT, if you've only just bought the unit then you are in luck - return it and get your money - back Magellan Support is extremely poor.

I am binning my Roadmate and getting a Tomtom720 Go series with maps and cameras preloaded - it auto updates when it is on its cradle attached to my PC/internet.

Bin the Magella - 4 years of problems!!!!

I had the same problem. Opened up the unit but did not see any loose IC chips. I noticed that the power lead goes into the cradle so I found someone who had a 700 series roadmate and borrowed their cradle and attached my unit to it. To my surprise it worked ok. When I tried to use my cradle on his unit it would power off by itself. I also found out by checking on a few user reviews that there has been lost of problems due to the cradle. Sounds like it not designed too well.
