276c Antenna connect issue
 
My older 276c was having issues picking up satelites with the stock antenna that is original to the GPS.

I picked up a Glisson external that, when it is working, picks up 12+ satelites where the stock antenna at best did 4-5

To get either to work, I have to repossion the antena (or cable), wait to see if any satelites are found and possibly move it again if none are found (which is normal and I have to try 4-5 positionings).

I'd have to conclude that something on the GPS side is the issue here.

Any words of wisdom about adressing this type of fault?

Sadly I had been planning on send in my 276c to Garmin for a refresh, and see I waited a bit too long... they don't reman these anymore

Have you ever replaced the internal battery that powers the memory? That stores info on satellites. If the battery goes bad, it takes forever for the unit to power up, find satellites, etc.

Doesn't sound like the classic bad battery issue, but you never know.

Thanks for the reply... I have my 276 hardwired into my bike and it never is off the battery for more than say hours.

Even unplugged it fire up pretty fast.

The normal operating battery has nothing to do with the "internal" battery that remembers the date/time sat info.

Even if the GPS stays plugged in and the operating battery good, if the internal battery is bad, when you shut off the GPS for extended periods of time (days to weeks), it forgets all the sat info and has to basically "cold boot" and reinitialize every time.

It's easy to check and see if the date/time when you boot it up is way off. Then you know you have a dead internal battery.

I get it now, and yes the clock has been way wrong in the recent past when starting up....

Off to google internal battery replacement. I'll update once I get this done and test.

Thanks for posting!

Internal battery replacement
 
There is a thread around here that shows you step by step how to replace the internal battery on a 276c.

I think Big Dog put it up, but could be wrong.

Oh, and just a note - you might not want to disconnect the screen to make it easier to work with. The tutorial doesn't talk about this, but if you do you could have big problems.... don't ask me how I know!

I have the battery on order, and replaced one on my old 176C years ago!

Well, the GPS clock showed the (very) wrong time again today.. good thing I have a new internal battery headed my way

I experienced the same/similar thing. I had tried to mount the external antenna on my handlebars then on a bracket I made and found that it wouldn't lock on a signal. I found that if I removed the antenna from the bike it worked flawlessly. I now mount the antenna on the top of my front fender and it works great.

My theory is that the Glisson Antenna grounds out or something similar and stops it from locking on the signal.

I didn't know they won't refurb the 276 anymore. Majorly bummed about that one........:cry
