Standard spitter can be used for regular TVs. If the signal degrades, it can be boosted with an distribution amp, and could go to 100 TVs on channel 3 (for instance).

Why is the screen is still black after I changed the battery whats next? Garmin gps nuvi2455

Make sure your new battery is charged. Start with the device turned OFF & disconnected from ALL power sources.
- Note: to make sure the device is NOT in standby mode (instead of OFF), press & HOLD the power button (for UP TO 60 seconds) to see if there is a prompt to turn it off.

Press & HOLD the lower-right corner of the touch screen (not the frame)
Continue to HOLD the screen, while switching the power ON.
- You SHOULD see a message on the screen about "clearing user data" after several seconds.
Once you see that message, you can RELEASE pressure on the screen and touch the YES icon.

The device should now Reset. Following any prompts that may appear, and then take the unit to a CLEAR area so that it can find the satellite signals. This can take up to 15 minutes after a reset.

No gps signal

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 Additionally, for instructional videos on many of the TND & RVND features please visit the Rand McNally You Tube page at

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:
Monday - Friday
7am - 6pm (CST)

My Garmin Nuvi 3790T will not acquire a satellite signal


Does the GPS work outside of the vehicle?
Where is the GPS mounted?
If the GPS is under the dash, mounting it up on top of the dash will help.
If the Vauxhall has a windshield with a reflective metallic coating or treatment in the glass, this may result in poor GPS satellite reception.

Tomtom wont turn on after chaging it

Reset your TomTom GPS receiver. Some TomTom users report occasional difficulty in getting their TomTom navigation device to start or respond to commands. If this happens to you, remedy the problem by performing a soft reset on your TomTom GPS. A soft reset will reset the data on your TomTom GPS receiver without erasing any data. To reset a TomTom GPS receiver, press and hold the "On/Off" button for 15 seconds or until the device restarts.

Let your TomTom GPS acquire the necessary satellite signals outside. If the device has trouble connecting to the satellite signals necessary for its operation, try an easy fix to the problem. Take your TomTom GPS receiver outside, away from mountains, tall buildings or heavy foliage, where the receiver has a clear view of the sky. Wait for a few moments while the device acquires the necessary satellite signals.

Portable Garmin GPS for car

Most problems for this happening stem from the unit being mounted on the windscreen when the windscreen has heating elements in it, this causes the signal from the satellites from reaching the gps unit. If this is the case, the only option is to fit an external antenna through the sunroof onto the roof.

Not receiving gps signals all bars are red

which means very low or no signal. There are a few things to check here...

1) Ensure battery is fully charged Via AC or USB.. ( the most common fault when no connection is achieved)

2) Ensure the BAUD and PORT are set as per the manual ( no brand supplied)

3) Poor position, too close to other electrical interference HT power lines, trees etc.

4) Damaged SIIRF Chip ( Never plug the GPS to car power when starting engine, damages Chip and battery and renders GPS unfixable

Try # 1 first as it is the common denominator in non connection.

Please rate my help++++Thanks for using FIXYA

Garmin Mobile PC cannot find gps signal when it scans for BU 353

You must make sure you are outside when you do it or in such a place that you can see the sky, as if you cannot see the sky, the signal cannot get to you, the GPS signal doesn't go through buildings very well. especially if low down. You need to set it up, with a clear path to satellite.
