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.

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 use to own a 700, i advise you to get the new magellan mastreo 4000 or higher,i did my research and the magellan700 roadmate is no longer being serviced.that is what the magellan website has had showed and someone on here also has said it and they start to have alot of problems.i own now a mastreo 4000 so far so good no problems.your choice
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
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.
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.
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.
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!
