Question about Magellan RoadMate 700 GPS Receiver

1 Answer

Broken RoadMate 700

My RoadMate 700 with relatively low use won't power up at all. I borrowed a cradle and it still is dead with both lighter and AC adapter. I own a multi volt-ohm meter if any guidance can be given.

Re: 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.

Power adapter for Magellan 700 is broken

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.

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!!!!

Magellan 760

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.
