Accidently chose wrong zone to unlock please help !!!

Hi!

You require a chart navigation or free viewer program on your laptop to decipher the information your GPS sends and to interface with it.

There are a few of these programs available, but we opted to purchase CAPN Voyager (The CAPN) many years ago and have been quite happy with it for the 16,000 miles of coastal cruising we've done. The program allows us to see our progress in real time on the computer screen and is easy to use

Prior to that, we used Maptech's free chart viewer which allowed me to plan routes and then put the lat/lons into the GPS unit, but had no interface with the GPS to allow us to navigate in real time.

Hope this helps.

Hi,
Go to the Safe Zone or Security Zone,
it will not have the lock on then,
if not known, Garmin will get the lock off it for you
Regards

I think you have to send it back to Garmin. Liam

problem solved by downloading and installing new software. Thanks

Contact Garmin.com and they will give you the unlock code.

you can not see the data card programmer as a drive in My computer , but you use Mapsource to send dat to your card

I just hardwired it into my vehicle, I use it for both road and water, I goggled garmin 276c wiring and I located the schematic. Unfortunately I cannot locate my printed hardcopy now. Give it a shot.

look on page 103

Garmin has updates for this issue on the website but it doesn't fix all the units. Mine for example still does the whole "charge complete" thing when showing 1/2 a battery. The funny thing is I let it drain and the unit stays on for about 10 hours after it says the battery is dead. Garmin is working on a new fix and they said it should be up in about a week.

Try skipping the installation wizard and use your coupon code to unlock the maps/GPS online at Garmin's website. 

Also if you downloaded the mapsource software online, the download may have been corrupted.  You may have to contact garmin tech support to try another download.
