Have you tried a Master Reset? It may help, but it WILL ERASE ALL OF YOUR FAVORITES. To do a Master Reset, turn the unit off. Press and hold the bottom right of the screen, then press and release the power button. Keep pressing the screen until the unit asks if you are sure you want to reset. Follow the prompts.

There are a few things you can try to restore satellite reception.
1. place your finger over the lower left-hand corner of the screen and hold it there
while pressing the on/off power button. Keep holding your finger there and a window should pop up asking if you want to go into maintenance mode. Select yes. There is an option called "clear user data". Select that option. It will not erase your favorites. It will however, erase any corrupted satellite data and will default you back to some factory settings. This will clear some of the memory allowing your Nuvi to collect new satellite data. Your Nuvi should reboot and it will ask you a couple questions like, timezone, language. Please select the proper settings.
Make sure the antenna is up and that you are outside. On the main screen, you will see a satellite bar graph in the upper left-hand corner. Touch the bar graph and you should get a satellite map, showing the satellites. If your Nuvi's receiver is working ok, you should see horizontal hollow bar graphs appear on the right. Eventually they will turn solid blue. This indicates they have downloaded the proper data from the satellite. When you have (4) solid blue horizontal bars (4 satellites), you will see the top panel begin to show improved accuracy and your Nuvi will then work as it should. This entire process make take 30 minutes or less.
If you don't see any bar graphs, your Nuvi may ask you severl minutes later, if you are indoors. If your outside, select no. It will then ask you if you have moved 1000 miles since your last use. Select yes. This will cause your Nuvi to start looking for
satellites, trying to locate your new position.
Now, if you still don't see any bar graphs, then your antenna may have a problem. There is a known issue with the Nuvi antenna where a part has failed, causing the Nuvi to no longer use its internal antenna and it's now always looking for an antenna at the external antenna port (the gold connector on the side of the Nuvi antenna). If you have a piece of small wire, a couple feet long, you can insert that into the center lead of the external antenna jack. Most likely, you'll begin to see bar graphs after a few minutes and your Nuvi will lock.
I haven't been able to identify yet, which part has failed. I am working on that.
However, if the piece of wire works, you can always go on eBay or a retail store and
purchase an external antenna for your Nuvi. They are magnetic and can either stick to your roof or any metal surface within your vehicle.
Here's another way to determine if your antenna has failed and will have to be replaced:
At the main menu, pres on the "wrench" symbol. Then press the "gear" symbol and then press "about". There is a field marked "GPS S/W". There should be a number next to it. It may be "2.9" or "3.0". That is good. That tells you that the main board in the GPS is communcating with the antenna receiver. If you see "0.0" then your antenna is defective and there's no way to repair it other than replace it.
Please let me know if I can be of further assistance to you.

a few things cause this to occur.
low battery power ( charge fully on AC )
no or poor view of the sky
Burned out SIIRF chip
The latter can occur when the unit is plugged in at the point where you start up the car, a spike can be transferred to the chip. all else works exscept satellite connection.
One should always connect GPS after engine is started, same with mobile phones.
If the latter, the unit is expensive to repair rewuiring a new motherboard. try getting it repaired under insurance, you dropped it, is the the entry for insurance damage description

When was the last time you updated the QuickFix of your TomTom? It helps your GPS to find the satellites.
Please, do the following:
1) Install "TomTom Home" software in your computer from www.tomtom.com
2) Start TomTom Home in your computer
3) Plug in the GPS dock to your computer's USB port and place the GPS on the dock. The green light on the bottom right of the GPS should turn ON to indicate that the GPS is getting power from the dock and charging
4) Start your GPS while being in the dock. If the GPS asks "do you want to connect to computer" answer "YES"
5) The TomTom Home software will detect the GPS and check if there are any updates for it. Then you'll be offered updates to install. Some are free, some are not. You choose the ones you want to install.
Please, report back if you need further assistance
