I have a 8 year old garmin GPS model 12 that may be dead. When I turn the red power button on the garmin sez "upload not present". Also the rubber at the base near the batteries has rotted. Thanks for any ideas - Doug

because it is old and dead.... no seriously, your cell phone doesn't last 6 years, why do you expect this to?
if it does not respond to a power button, powered into a car or plugged into a computer, the unit is toast.

Sorry to hear of the dead units. Are you using the correct power cable with a small hole in the centre of the plug? The GPS 12 is strictly limited to 7 volts only. The accessory cigarette lighter cable for this model has a circuit inside to drop the voltage from 12 to 7. Cannot be fixed. There would have been a plastic peg in the back of the GPS socket to prevent anything but the correct voltage Garmin cable being plugged in. Unfortunately these pegs are easily broken off. Yes, they are a good little unit even though well on in years. The next model up - the 12XL - can accept a wide voltage range and does not have the plastic peg.

All the best, Tony at KiwiGPS.

Call Garmin customer service, they are wonderful. My rubber thing around the outside became loose,and they sent me a new unit, even though it was almost 2 years old.

Go and grab a garmin serial lead from somewhere and go to the following link and download the VER4.6 software.

The Garmin web dater may not work because the unit may already have had Ver 4.6. If it does then the web updater will tell you that you already have the latest verson on your unit and won't proceed any further.

You need to download the 4.6 updater by itself.

Hope this helps

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.

Stay clear of rechargeable NiCads as they supply to low voltage and you may experience cutouts ? Use good quality regular alkaline batteries. Check battery terminals in gps (both ends) for corrosion/rust and clean if necessary.

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
