Re: navman icn510 gps reciever problem
How long are you waiting and are you moving while it is trying to acquire signal? These receivers are using older circuitry that may take up to 20 minutes to first acquire a signal from a cold start. If you are moving it may take longer!!! The good news is that after you have initially acquired a location, if you turn the unit off it will only take a minute or so to reacquire after it has "warmed" up.

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. 2
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.

Usually, after you turn on the GPS device, it may take a minute or so to start up and lock into the satellite signals. While it is waiting to get a valid GPS signal, it is "listening" (scanning) for satellite signals to establish your current location. If you are in the open outdoors, i.e. not inside a building or under extended covers, it should get the satellite signals within a minute or so. If you still can't get a GPS signal, consider shutting it down ... using a "hard" shut-down (hold down the on/off button for 5 seconds or more ... to re-boot the system/software programs. Then, wait a while before starting it up again. Make sure your device is plugged in and/or the battery is NOT low when you're doing this.
1) BAUD rate and PORT are incorrect 2) GPS not in clear view of the sky 3) Battery is too low to receive signal.. Recharge using USB or AC charger before trip 4) Siirf chip is damaged from plugging in gps when starting the engine, this will damage the chip beyond repair Please rate my help++++Thanks for using FIXYA
Not sure if this will help you or not. GPS needs a clear line of sight, tall buildings, bad spot in your car or on your dash, weather conditions and pink elephants all will interfere with the GPS signal. Keep the unit low and as far forward as you can so that it has the best chance for signal. Best position i have found is 3-4 inches above the heater vents on the dash and directly in front of you since this is the spot that is generally unobstructed by anything. One final thing, sometimes you have to shut them down start driving then turn it on, they do sometimes lock themselves up and out of things. Don't know how or why but it does happen. See pink elephants for better results. Hope this helps
The waiting for signal message just means it can’t get satellite reception where you are. you most likely need to utlize the Optional external GPS antenna. This is a common problem in the midwest and southwestern states. if this has happened since you bought it. the internal antenna couldve come loose. Which means you may have got a defective unit from the factory. But my guess is you just need to utilize the external antenna.
its like thinking of a cell phone and how some people dont always get a signal. now in gps it needs 3x the signal. with 1/8th of the communications satellites cell phones have. so as more and more people get tom toms the harder it is for each unit to work, and less signal can be partitioned to your unit at the time of use. where as cell phones only need 2 towers, GPS needs 4 satellites.
