My gps 12 haS PROBLEM IT SAYS ( UPLOAD NOT PRESENT , WHAT IS THE SOLUTION ?

Here is where to download the manual: http://static.garmincdn.com/pumac/82_OwnersManual.pdf

From what I see, I would say no, it appears that the datum is hard loaded.

It sounds like it has lost its memory battery. Usually you
would get a "memory battery low" message as it is on its
way out but you don't mention that so perhaps it has
completely failed.

The battery is rechargeable - if you leave it switched off
and loaded with a fresh set of alkalines for a few days it
may recover. If not contact Garmin as they have replaced
many memory batteries free of charge even out of warranty.

you need the mapshare software installed to upload the map

I had the same problem and it took me some time to make my cable. I got this info from fix ya. Reload the software for your unit, I googled garmingps12 and went to downloads from the garmin selections.The software is not compatable with vista, so I ended up using my old computer to do the job. http://pfranc.com/projects/g45contr/assemb.htm
This web site gives good information on making your own cable.
I hope all works for you as it did for me. justaxiom

If you haven't used the gps for a while they can try to operate with the incorrect catalog or time. Unless these are both correct it gets lost. Usually you can correct this with a forced reset. There is also a update for this unit which also forces the update.

The data cable sort of screws on and makes contact with 4 pins. This is the little round connector. It does both power and data. The cable is a wee bit pricey from Garmin but you can make them or just get one from ebay.
The reset usually wipes out any saved routes poi's etc so using the data cable will save all of those. To reset the 12 I believe you hold the lower right corner of the screen and then power it on to reset. Then you need to let it rub until it gets the new data which can take 5-50 minutes. Makes sure your batteries are good.
I'd recommend the data cable route (use a 'gasp' non garmin cheap cable) and upload the update at the same time and you should be good to go try and get lost again.

Hi...once i was asked the same problem!....and we couldn't do anything...i think you lucky because...the one who asked me about the same problem crashed his software forever...i recommend you to go for the warranty...and not to attempt any update...

I think I found the solution to everyones problem of "upload not present" message on the Garmin GPS12** when trying to update the Firmware. I'm really busy - just picked up my daughter from the airport and a million things to do. I will post again in detail maybe later today-tonight.

I would say that it has a bit of Umzumbe fever probably from the water it sucked up when you failed to warn me that it was in my pocket when i jumped over board, a bit like a beer can, no upload available
