My gps is not working on tnd 520 - GPS

I use a TOM TOM GPS, and they have an online Homepage that you can download any updates. I would imagine yours is the same. Look up the Rand TND520 homepage on the internet and look for a PC setup program. With the Tom Tom, I have to connect it to the PC with a USB cable and it automatically downloads and updates itself.

Ask Rand Mcnally

Hello Johnny,

A quick search in the Rand database shows there is a record of you registering your device, however we don't see any service tickets. Have you called Technical Support with your signal issue?

The answer to your question and many others can be found in the FAQ section on our support page at www.randmcnally.com/support. Additionally, for instructional videos on many of the TND & RVND features please visit the Rand McNally You Tube page at www.youtube.com/randmcnallyonline.

The issue normally occurs when device does not have a clear signal view of the sky.

Your device requires a direct line of sight between the receiver and the satellite. When an object lies within the direct path, accuracy suffers due to reflections and weakening of signals. This can be the cause of lost signal in urban environments, within valleys and on mountain slopes. In all three situations, the objects (buildings and the Earth itself) are substantial enough to completely block the GPS signals. When weak signals are received, they may have been reflected off buildings and the surrounding landscape. Reflections generate multi-path signals arriving with a small time delay at the receiver. This results in inaccurately calculated position.

To troubleshoot a signal issue we first suggest you reposition the device in the vehicle and allow it a couple minutes to recalibrate its new position. If there is no signal in the new position, step outside the vehicle with the unit. Perform a reset by pressing the reset button. (Found on the side or back of the device depending on your model) When the unit powers up, allow it a couple minutes to recalibrate its position. If the unit receives a single outside the vehicle but not inside, than there is something interfering with the GPS signal. Do you have a large windshield overhang? Do you have a dash camera? A satellite radio? We suggest turning off those devices to see if your unit will receive a signal.

Please call us if the unit continues to fail with receiving a signal after trying the above recommendations.

Need details... What's not working? The unit doesn't boot up or you can't route because it says your map files are expired?
If it says your map file are expired, you will have to call Ray Allen @ RM Tech Support at 877-446-4863 and have them email you a new navigation.lic file.
It goes in the navi/user folder and reboot. reconnect to computer and delete the bin and layout folders, reboot, reconnect to dock and update it via the TND Dock software.
If that does not work, they will have to send you an SD memory card with a new program on it to install into the TND 500. This will erase EVERYTHING and restore to an "out of the box" condition.

Try pressing the reset button on the back or the side of the TND. If it still will not power on contact Rand McNally support. Be sure to have your serial number handy, (back of TND, bottom right)
