I know this has been discussed here before but I can't find it. I was up getting the boat ready today and when I hooked up the Garmin plotter, it would start up fine, acquire the satelites fine and then after 45 seconds- 1 minute, the unit would power down. It did this a half dozen times.

Anyone have any ideas what the problem might be and how to fix it?

Thanks,

Tim
 
I had the same problem with the same GPS today. After about five trys it finally stayed on.

Same occasional problem with mine too. My working theory....the Garmin 172C is female.

Wow, that's odd. I have a 176C and the same thing happened several times my last time out. Powering itself down. Double checked connections, no problems found. Will see what happens today.
 
This an older unit and I think you need to down load a software update because of the new reverance bird that is up there. There is a way to turn off waas and that will stop it from crashing, call Garmin they will walk you though all this.

I had the same problem and called Garmin support. Apparently there has been some change to the satellites and to get it to work, you need to disable WAAS when the unit first starts up looking for the satellites.

The newer units work fine.
 
Not this again. The 172c is my main unit, and we're trying to cross back to Florida from the Bahamas this week. Ugh. However, I carry a Garmin Colorado as a spare (ever since last year when these units started acting up), so at least I've got that in my favor. I did have the problems everybody else here said they had last year, but nothing so far this year and we've been using the unit daily for the last 3 weeks. But I did upgrade the firmware a couple of months ago. Try that. You can find it on Garmin's website. It's easy, quick, and free. If you can't figure it out, Garmin tech support is very good. Call early in the morning as they're also very busy.

Mixman,

Thanks, one question. How do you hook the unit up to your computer to update the firmware? I don't remember there being any USB ports or anything like that on the GPS. I'm heading up after work and I'll pull it back off and take it home with me.

Thanks,

Tim

I have a Garmin 152. The tide data chip ran out. Garmin said I can download new tide data from their web site with a $60.00 cable they can sell me. The power cable has about 8 pins in it and some are used to reprogram the unit. The cable they sell plugs into where the power cable does and the other end your computer.
