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.

Technical Support is available:

My gps freezes when on speedo


Okay. I have to explain what happens when you use the speedometer option. While it is off, the GPS use using less cycles per minute to get the location from the satellites and sometime from ground beacons. When in speedo mode, it now needs more processor, memory, graphics speed and the power needed for the receiver. Now the unit is running about twice the cycles per minute to provide an accurate location to judge your speed.
How to work around this.
Best answer: Dont use this option! Its simple and you dont have to burn your noodle worrying about it.
2. If you must use it, then go into your display and map options and turn the map details and quality down. This will free up memory and CPU speed.
3. Turn tracking off. This will free up memory and CPU speed.
4. Use Garmin's mapping program to only load necessary map locations.This will free up memory space.
5. Be sure you are updated to the latest map data and firmware.
6. This can also be caused by the location of the GPS in the vehicle. On the main screen of most Garmin's, you press and hold on the corner near the icon showing the GPS signal. It will go to a more detailed screen of the satellites and signal strength. Stay in one place in an open area like a parking lot. Let the GPS locate itself first. Then relocate it where you can easily see it and you see 40% of signal or more from 4 or more satellites.

Tip

Satellite signal taking ages to come up


If your tomtom is taking ages to find a satellite signal, it may just need the GPSquickfix updated.

You can get this updated using the Tomtom Home software thatcame with your device or you can download if from the Tomtom website.

The reason this happens is that the satellites are constantly moving on different paths etc and the GPSquickfix files is updated weekly with that weeks satellite paths.

I'm having the same problem and i have had it in the car with nothing around for a day now and still it says waiting for valid GPS signal.


Does the device work outside the car? Remember, the GPS does not work through the roof of the car; clear sight through a window is needed. Some car windows have metallic coatings that can severely reduce GPS signal quality.

You should also connect the GO to a PC once a week and update the "QuickGPSFix" data using the TomTom Home software. It contains precomputed GPS satellite positions and speeds tuning in on them down to seconds instead of the 10+ minutes it needs without this data.

Waiting for a valid gps signal


A couple solutions:

1) Make sure the TomTom can "see" the sky well... the GPS satellite waves are rather weak and easily blocked by trees, and anything not a window.

2) Hook up your TomTom to the computer (see details at www.tomtom.com or in the manual)

2b) Do a "sync" and download all updates. One of the updates is a small file that tells the TomTom where the satellites are located this week, and helps it sync up much faster. The longer time between uses, the longer it takes TomTom to find the satellites, and that can takes up to 2-5 minutes sometimes.

That can be frustrating with a car full of people waiting to get going and the driver doesn't want to drive without making sure the TomTom works and is giving valid directions.

Waiting for valid gps signal


The GPS needs at least 3 satellite signals to operate.You are probably in a bad reception area. Move around a bit and try again until you see a signal array of 3 or more!

Garmin NUVI 650 acquiring satellites


  • Make Sure the GPS has a good, clear view of the sky. “Clear” does not need to be sunny. Overcast skies have no noticeable impact on GPS performance. But buildings and trees do. So take the GPS outside where you have the biggest sky view as you can.
  • Next, wait for the GPS to acquire a signal. If this is the first time you have used it, expect it to take up to 20 minutes to find a signal. Most often it will take less, but prepare for 20 minute. Now for an important step… Once it has found your location, let it continue to sit there for about 30 minutes.
