On Sat 21 Nov I disconnected the unit and checked to make sure no pins had snapped off inside the connection port, I then connected the unit to a spare power cable in the garage(it has an in-line fuse and ac adaptor fitted), powered on the unit then scrolled thru the various menus powered off unplugged the unit, then re-connected it back in the boat and went for a cruise up the local river yesterday Sun 22 Nov and the unit worked fine, so my guess is a good as anyone's as to how it was fixed, most electrical appliances have gremlins of some kind, could have been low power from the old battery(replaced it), I definately checked and re-checked the connection though, mine are covered in vicks vapour rub (a suggestion from Navcom - local dealer for raymarine).cheers and many thanks

Hi I have a Magellan 320 that I have owned for 7 yrs. Due to the purchase of a chart plotter I have not used the 320 for about 2/3 years. Having switched it on this week the unit failed to gain a fix to...

I believe you have to input your location lat & long so that it knows basically where it is so that it can decide which sat's to use. Hope this may help.
I have bought a 2nd hand 320 and want to upgrade to software V 3.15
I see you've done this with yours - can you tell me how to do it and send the s/w, please? Regards, Ron. Kerikeri NZ

Gpsmap 180 firmware corrupt

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.

My garmin nuvi 780 shows me at an address a good half mile down road from my house. Also, the lat and longitude it shows me at while i'm home is 15 miles from where i am. whats wrong here and how do we fix...

The accuracy of any GPS device depends upon having good locks on multiple GPS satellites (at least 4, but up to 12 on many units).

The main screen on the nuvi shows the acquisition quality in bars (like a cell phone), but provides no further information. If you have 5 bars, your accuracy should be much better than what you report. Ideally, it should be as good as 4 meters (13 feet), though that will vary depending upon the current configuration of GPS satellites overhead.

An error of 15 miles should never occur. How confident are you of your actual latitude/longitude?

Garmin gps 12 wont turn on.

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.

Magellan Triton 300 GPS handheld

This problem is caused by two possible problems. First go the MENU>>VIEW>>SETTINGS>>MEMORY and CLEAR YOUR MEMORY. If does not work and the unit is NOT seeing any satellites in the satellite screen, then you most likely have a defective GPS+ANT. Unfortunately, this is a part of the motherboard and cannot be repaired.

GPS screen went blank

My problem exactly. Unit would start up, acquire satellites, then the screen would go blank with a single vertical line. Unit would not respond to buttons or even turn off. Unit works fine after I did the reset:

- w/unit OFF, press and hold QUIT+DOWN+MENU
- press and release the power button, release DOWN, keep holding QUIT+MENU for 5 seconds.
- unit prompts something like: "erase all data;" choose yes.
- you will lose waypoints, etc.

Go to the Garmin support area for details.
