Magellan 315 won't find satellites.

i have the same problem too, anyone has any idea. please share with us.

GPS SYSTEMS HAVE A TENDENCY TO LOSE CONNECTIVITY TO SATILLITES BECAUSE OF BAD WEATHER, CLOUD COVER, TUNNEL ENTRANCE, BAD OR NO POWER, BATTERY LIFE HAS BEEN EXPENDED, HAZARD OF ELECTROMAGNETIC INTERFERENCE TO GPS SYSTEMS, AND IMPROPER VEHICLE MOUNTING AND HAND HELD POSITION. FREE SOLUTIONS 1. ALWAYS PLACE YOUR GPS DEVICE IN THE UPPERMOST PORTION OF YOUR VEHICLE SO THAT THE GPS SIGNAL MAY EASILY LOCATE YOUR DEVICE EVEN WHEN THE WEATHER IS BAD 2. KEEP YOUR BATTERY CHARGED ONLY WHEN IT NEEDS IT MOST AND AVOID CHARGING OFTEN 3. IF YOU OVERCHARGE YOUR GPS DEVICE, YOU WILL EXPERIENCE BATTERY LEAKAGE, WHICH CAN EAT AWAY AT YOUR CLOTHING, DESTROY YOUR DEVICE IN SECONDS, AND CAUSE DAMAGE TO YOUR VEHICLE SEATS 4. YOUR GPS DEVICE HAS A TENDENCY TO FREEZE BECAUSE OF THE SIM AND MEMORY CHIPS LOCATED WITHIN IT 5. YOU CAN FIX THE FREEZING PROBLEM BY REMOVING THE SIM CHIP AND MEMORY CHIP AND RESTARTING YOUR SYSTEM 6. OTHER FREEZE PROBLEMS OCCUR BECAUSE THE DEVICE IS COLD WHEN IT IS KEPT IN THE VEHICLE AND CHIP CREEK OCCURS WHERE THE DEVICES MICROCHIPS BECOME LOOSE AND TIGHTEND BECAUSE OF WARM AND COLDER AIR FLUCTUATIONS. IT IS BEST TO KEEP THE DEVICE IN A PURSE OR ON A TABLE WHERE IT IS NOT SUBJECT TO CONSTANT TEMP. CHANGE 7. PREVENTION OF ELECTROMAGNETIC INTERFERENCE IS BEST SOLVED BY: interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common

I believe you have to input your location lat & long so that it knows basically where it is so that it can decide which sat's to use. Hope this may help.
NOW - CAN YOU HELP ME?
I have bought a 2nd hand 320 and want to upgrade to software V 3.15
I see you've done this with yours - can you tell me how to do it and send the s/w, please? Regards, Ron. Kerikeri NZ

Not a fix, shared information.

Yes these units have an internal ten year lithium battery. I am currently researching this issue, as I have two dead and one working 300series GPSs. When the internal battery dies and the regular batteries are removed or die the unit will loose all user data (way points and routes), as well as the satellite map and initialization. After dieing the unit will appear to function normally but fail to lock on, track or get a fix. Only showing the coordinates from the initialization. These units also have an internal capacitor that provides sufficient power to hold the memory during quick battery changes, but not over night. I have as yet found a working solution, but only researching this for a few days.

Occasionally, a unit will need to be reset. This can be due to software errors, firmware updates or simply at the command of technical support staff. A reset either will restart the unit, possibly clearing up any minor errors, or will restore the unit to the settings it was built with. There are three major Magellan units, which utilize different methods to perform this task.

Things You'll Need:

• A thin object (such as a paper clip)

Using the stylus, tap "Main Menu" and select "View."
Tap "Settings," and select "Restore Factory Settings." You will be given the option to confirm this action. Be sure that you want to reset to the settings that the GPS was built with. This action is irreversible.
Tap "Confirm," and the unit will begin to reset.

Maestro/Roadmate GPS Units
Locate the button marked "Reset" on the left, right or bottom of the unit.
Using a thin object, such as a paper clip, depress the button for two to three seconds. The unit should reset.
If the unit does not reset, immediately press the button again and hold it for up to 10 seconds.


Tips & Warnings

• Do not attempt to perform a factory reset on the Roadmate or Maestro GPS units by holding down both the "Reset" and "Power" buttons. This will cause the GPS unit to format its own hard drive. Doing so will erase all data, including the GPS software, from the unit.

Hi1 Here's the link for your manual!

Good luck!

There may be a few reasons for it not locking on
'1) batteries too low
2) Sirf chip damaged
3) Not in an area where it has a clear view of the open sky
4) electricasl interference from other electronic products
5) High voltage power lines overhead

The only method I have found is with a dremmel tool and cut it open along the original split line.

All the electronics are clear of the case mid line. The case is a bit less than 3mm thick.

The antenna is closest with maybe a 2 mm clearance all round and the various (6) rear conector wires (on the right looking from the back) have a similar clearance but sit below and away when the unit is assembled. Cheers

I own Two Magellan 315. They both have failed in exactly the same way as yours, will not lock on too a satillite. I have concluded that this is their design life and that is the end. I did post one to the Magillan repair centre in France but that disappeared. I have replaced the two of them from EBay and will see how I get on with those
