Default Question about GPS signal

Does anyone ever have the issue where it takes a while (up to 30 minutes) to get a signal on your GPS? This seems to happen to be only early in the morning. Fortunately it takes me about 30 minutes to get to the jetties from my house, so it is working by the time I get offshore, but it is stressful waiting for it to get a signal. It never happens in the afternoon for some reason. Is this normal????

The only time a GPS takes that long to lock in is if it has absolutely no idea where it is......as in, the internal batteries are dead. The time of day has nothing to do with it.....

Something is not right! I would call the support number for your GPS unit and tell them what's happening.

Thunt55,What manufacturer and model is your gps?Some older units did take a long time and also can lose their almanac. I will be glad to help as soon as I know what you got.

Where is your antenna mounted? Is it possible it is being shadowed by obstructions on the boat until you turn a certain way and that's when you get your signal?

From a completely dead cold start the minimum time to full lock is 12.5 minutes (and there's a good reason for that time period ) plus the odd minute or 2 to go through the motions. Much over 15 minutes max would generally indicate some type of a problem, somewhere?

Morning, noon or night doesn't matter.

Cheers, Kerry.

I'm having the same problem, however I do not leave the dock till mine is working. My latest thought is that it may have something to do with bringing it out of an airconditioned environment into a hot and humid one. The last time I used mine the unit was left locked in the cutty, so it did not have to aclimate itself. That time I had instant signals.

It is a Garmin 182 (bought in 2001). If it is the internal batteries as mentioned above, could they be replaced inexpensively? As I mentioned, it only happens sometimes, and after I leave the boat house, it has a clear shot to the sky the whole day. Thanks.

AT one point I felt it was my connections on the back of the unit, and it my still be that. This is very frustrating!!!
