I have had this Garmin 2010c since new. This year it started loosing signal from the GPS antenna. On bootup, the splash screen shows the antenna, and the GPS will come up, but after about 30 seconds the signal is lost. I have been through the connections and fuseholder, even temporarily removed the fusholder from the circuit, with no luck. Also stripped the cable insulation back about 12 inches looking for corrosion and found no issues, remade the ground connection as well. The connector to the back of the 2010 looks fine. The unit consistently looses signal in 30 seconds or so.

Is there a known problem with the 17N antenna where it fails after warming up?

I had the sister unit (2006C) which I purchased brand new back in 2004. I had to have the antenna replaced after 2 years (out of warranty @ the time) I just sold my Eastern 24' with that unit & sometimes I noticed it would take anywhere from 3-7 minutes to aqquire all of the sats. Some days were better then others. If you need parts, that's going to be tough @ this point. A "google search" is your friend @ this point. Maybe it's time for an upgrade!

As I recall that 2006C cost me like $1900.00 just for the chartplotter, then $200.00+ for the antenna & another $300.00 for the sounder. Hell....You can buy a 10' now for like 40% less!

Yes, this is a problem I've witnessed more than once with this antenna. The good news is for $69, you can have a brand new antenna from Garmin. We just sent in 3 bad 17n NMEA 0183 antennas and got 3 brand new 17x NMEA 0183 antennas @ $69 a piece which is their flat rate on those antennas. Here's a good place to start:

My 3006C did the same thing last year. It also displayed the date as May 1992 and was not displaying accurate time (no adjustment for daylight savings time).

I had never upgraded the software (new in 2005), upgraded the software and it has not lost the antenna connection since.

Have a 2010c on the dash of the little boat and Turned it on for the first time last week and nothing. No sonar no gps but I am not getting a light on the sonar box, even with the wires directly connected to the battery. Did the same thing you did, went back through all the connections and nothing. Talk about strange....;?

My 2010c died lastmonth:-) I'm thinking that over the years the connecting plug tabs have worn down and are causing the GPS to lose the signal

That is possible, easiest way to check for that is to go to your satellite screen, move the plug by hand, and see if you lose all your sats.

I ordered the new antenna from Garmin. That is a good buy, $69 for an updated 17x unit. Thanks again. I was getting ready to try a Chinese generic from eBay.
