Re: Loss of GPS signal

Fred... be more specific in your problem please. It turns on and won't locate your position? Or does it just take some time? If it takes time, how much time are we talking about? Under the menu "gps status" how many channels are you receiving and do you have azimuth and elevation? Are any of the channels ALL zeros?

Try undoing the satellite cable at the back of the box and put a kink in the centre wire so as to make better contact and re,screw back on., do this while the unit is turned off. We had this problem and this cured it.

GPS wont aquire a satellite

    Hello there and happy new year
    If Your Unit Cannot Acquire Satellite Signals
  1. For your Garmin GPS unit to acquire the satellite signals it needs to function properly, the unit must be taken outside, away from mountains, tall buildings and heavy foliage where it can get a clear view of the sky. Keep the unit stationary for several minutes while the GPS unit acquires the necessary satellite signals.It may take several minutes for the unit to locate a good solid signal
  2. OK
  3. Hope this is very helpful please keep me posted on this ok?
    Best regards Michael

Hi There, Just bought a new Nuvi 255, I was just driving to a destination and out of sudden, my GPS got a message mentioning, loss connection to sattelite. It stayed on for like 30 mins, till I reach my...

Unless you are driving in a dangerously remote area of some desert, or a large city, GPS units rarely lose signal. Chances are you have a defective unit, I'd contact Garmin support: Here.
Hope this has been of some help.

Garmin Nuvi 205 Problems aquiring stellite

usually gps are automatically sensing the signal, with clear view without and sometime even with minimal obstruction like trees windows etc. there is no other way your gps could not acquire signal unles it is having a problem .

all gps thesedays have 10-20 meter accuracy, it is only a receiver, this model particularly have the highest signal.

in other words i suggest you reset your unit from the bottom and see if there is any improvement, replace the unit

Satellite loss

How long has it been since you updated the firmware on your unit? Try updating and see if this helps. Also, keep in mind the receiver on the C330 is not as sharp as on other units like the C550 and some of the Nuvis. You may have problems while under overpasses, between large trees or buildings, etc. This is just a design limitation of the unit.

Loss of signal after about 10 minn of time

If it happens around the same suburb the sattelite can't get to that area.

Or it is programmed for another location meaning : it wont display most of the places near you.

Or if its old it wasn't programmed with all the streets as new streets do get built alot.

Also this GPS is a pretty bad one as I am already dealing with 5 others They are all 660s and are the only GPS with problems.

Hope this helps - Josh

Loss of signal

Leslie, Not updating your GPS isn't going to cause signal loss. Push the options key, go to configuration, then to diagnostics, scroll down.. select reset gps. it will say it takes 5 min. to relocate.. etc. see if that fixes it. If it doesn't fix then when you restart your unit and the user menu appears. Press "-" key and "repeat" button at the same time.. then select clear gps user data or.. user data gps... something to that nature.. Hope this works out for ya. -Dan
