Aquiring a GPS signal

I have a Magellan Roadmate 760 and when i first bought it it worked just fine. Now it seems like when i turn the unit on it takes a long time for it to aquires a GPS fix. This happens every time i turn the unit on. It can be a sunny day driving down the highway and it will take 20-25 minutes to aquire a signal. After it aquires a fix it's ok until i turn the unit off. When i first bought it the unit was very quick in aquiring a signal. My Dad has a Magellan Roadmate 800 and he says he is having the same problem. Any suggestions would be appreciated.

Daniel,

My 760 would not acquire a signal as well. When I opened the unit, I found that RF cable loose on the PC board in front of the HDD. The contact the RF cable snaps into had broken solder joints, which is amazing when you consider that this tiny connector is soldered to the PCB in three seperate locations. Let me add that if you don't have a lighted magnifying glass designed for this type of work, be ready to take it to a technician that does!

Anyway, I just wanted to say thanks for your expert advice and that I learned two valuable lessons over the last six months.....determine where a company's tech support resides befor spending $1000 and save your frustration and do your own research on the web.

Thanks Again,
Greg

    Hi Daniel,

    I opened my unit and found the gray clour RF cable is out from I/O. Now I am not sure really where exactly this will connect on I/O.

    I will really appreciate if you let me know if you have any information.

    Thanks

Ggleed, On the 760 unit, I would try: After resetting GPS user data, make sure the problem still exists before proceeding. 1. Resetting GPS user data- At the user menu press the zoom out key (-) and the repeat button at the same time. Once the menu appears select reset GPS user data (that may or may not be verbatim but it's not the Reset user data one). 2. Reset user data Resetting user data will cause you to lose all of your POI's and user information, which of course can be re-entered manually. So, depending on how much info you have on your unit and if the time delay is that much of an issue you can do the same process as before except this time do select reset user data. 3. Check RF cable connections This involves opening the unit up. This is at your own risk. Once the screws are out you will see a either gray or black cable going from the main board to the I/O board (the board screwed into the rear housing) Check both sides of this cable as the side on the I/O board has a history of either coming undone or the soldering on the I/O board connector is loose. Unplug each side of the RF cable to make sure the solder connections are solid. If this is the problem, then you need to either find a soldering iron or find someone who can re-solder it for you. This is not an uncommon find in the 760's. Hope this helps! -Daniel

No signal in two units, did reset with magellan tech service, still gets stuck in the same location and no signal


Plug it in, turn it on and let it sit out in the open. If the unit is working at all, it will eventually find and lock onto the satellites. The 760 I'm using now came from California and it took over 2 hours to lock on. When I start a trip now, I let it sit before starting to drive and it locks on in just a few minutes.

I need an upgrade for my magellan Roadmate 760


You can download an upgrade for this unit from the Magellan website for free. Maps can be upgraded but they cost about $80, and that doesn't seem worth it to me. See if that works for you.

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.

Unit will not acquire the satellite signs


FYI ....My Roadmate 760 would not aquire a signal, I went to diagnostic screen and found it was detecting/tracking 0/0 satellites. Held the plugged in unit out the window and within 10 seconds was tracking 7 satellites! Turned out my 1999 Olds Silhouette Van has a anti-glare filter inside the factory windshield that blocks GPS signals.My wifes 2001 Chevy Impala also has same type filter. Check your windshield, filter is visible inside glass to within about three inches of edges of glass. Worth a look.
