Question about Magellan Roadmate 760 GPS Receiver

2 Answers

Magellan 760 Hi, my Gps has trouble staying on. Its obviously somthing to do with the power supply because when i wiggle the wire i can get it to come on. But... when i drive over bumps it will lose its connection and shutoff. Do you think getting a new power cord will fix it? The green light is always lit at the ac its just the connection at the unit thats seems to be the problem. please get back to me as soon as possible. Thanks Dave

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.

Dave, I'm about 75% sure it's a small IC chip on the backside of the I/O board. There's 3 small SMALL.. chips in a row on the backside where the last one closest to the end of the board rubs up against the outer rear housing. If your unit's out of warranty and want to attempt to fix it yourself atleast try to ground yourself when taking this on. You'll need to re-solder the chip back on. Before undertaking this, make sure that it's not something simple such as a loose connection between the power source and your unit. -Daniel

How can I get the code to unlock the European map Magellan Roadmate 760

You will need to pay Magellan for the authorization code, they are the only one that can provide you with an EU code for your Magellan 760 RoadMate. Sometimes Auto Nav 2000 Plus, Inc can also assist. They have direct connection with Magellan to assist issues with Magellan products. Good Luck

Magellan 760 does not find satellites

I recently i had the same issue. Open the four screws from back. remove the back cover carefully (tahe care of the attached cables).

check the atena wire connection (gray thin wire). both the ends should be seated firmly.

in my case, soldering at one end was broken. had to resolder. its working now.

The weakness of the 760 is the cradle. Is the power wire or the cradle loose or wiggles? You may need to buy a new cradle if that is the case. They are expensive. I soldered my power wire right into the cradle and it worked fine.

Magellan Roadmate 760 map update problem

Just push the antenna firmly back into the base; it pivots on a coax connector.
This is typical when you drop it.
The antenna is removable.

Magellan GPS does not turn on

I've got one that has a problem with the power connector. Look on the adapter thingy (has the female power socket along with the usb socket). With a pin, wiggle the center power pin. If it is loose, this is the problem. Carefully use a knife to open the adapter thingy (it's glued together). Go to Radio Shack/Fry's and get a replacement power female socket that solders to the little PC board in the adapter thingy. This will fix it. Allen
