Question about Magellan RoadMate 700 GPS Receiver

1 Answer

Lost power- will not come back on

I was using my Roadmate 700 when the power went off. This has happened before when the power cord pulled out-but simply replacing the cord end back into the receptacle on the side of the unit brought the unit back on. This time, however, plugging the power cord back in and pressing the on button didn't bring it back. The power cord plug has a red light and it is lit when plugged into the cigarette lighter receptacle so there is power at least at the point it plugs into the cigarette lighter receptacle. Question- are there any fuses in the unit that I can check and replace if necessary? Thanks for any help you can give me on this problem. Dan Ferguson

Re: 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.

Had the same problem with my MRM 700 back in 2005, only 2 months after I purchased it. They changed the connector, and it worked. BUT, few months later I had the same problem again. I haven't used it anymore since then (moved to another country), now I am trying to fix it but no warranty anymore..

I had the same problem. It was the pin inside the **** clamp that was broken. As I wiggled the plug in the unit the pin would dislodge. eventually the pin got lodged in the 12v power cord.

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!!!!

Roadmate 700 wont power up anymore

I had the same problem. At first intermitant and then permanent. The power connector inside the based that the head unit snaps onto had the center post fall out. You need to removed the 4 small screws located in the threaded reseases. Then using a knife I pried the plastic halves apart. You need to break the ultrasonic bonding on the plastic, but everythign seperated where it should. Now you have access to the circuit board. I soldered in 2 wires which I brought our and soldered to a cigarette outlet cord. Then I screwed it all back together.

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!
