I have a Nautilus NT GPS that has been out of service for a number of years the boat was vandalized and one of the few things left unharmed was the GPS. Unfortunately, the manuals were destroyed and how the device was cut away I would like to know what the wiring diagram should be so I can install the GPS on a 15ft run-around skiff.

use google to find manuals for things not supported,
manuel = manual? so is not name, VANDAL DOCK.
I guess you mean this,
Vandal Speaker Dock
at least 7 years old, for cell phones of some kinds.
in 2013 amazon poster said scullycandy support is Zero.

you should look on your paperwork (title or registration) this will appear on there if the whole thing was purchased/restistered as a unit.. if the motor was added to the boat.. there should be markings cast into the motor in a few places like the transom clamp and on the side of the block..

Hi Steve,

The Street Pilot line was one of the first automotive GPS devices from Garmin, and has got to be 8+ years old. Garmin contracts with Navteq for map software. At one point, Garmin needed to have Navteq compress their new maps so that they wouldn't need to increase the amount of memory in the GPS units and still be able to include all the way points, and new features such as junction view, traffic receivers, text to speech voices, etc. These new maps have an "NT" descriptor in the title. "NT "stands for "New Technology". Non-NT maps are no longer produced.

The new Garmin GPS hardware had to included the ability to decompress maps "on the fly" for display on the screen. As a result, the NT maps will not work in the older Garmin devices.

Your best bet is to either use the Street Pilot - knowing that the routes may no longer provide accurate information, or purchase a New, Refurbished or Used GPS. Garmin offers "Lifetime Maps" as an option for nearly all NT capable GPS units either as a subscription after GPS purchase, or "in the box" when buying a Garmin GPS. You'll get FREE map updates for that GPS up to 4 times per year. This assures you of always having the most recent maps available in your GPS. Look for a model that has "LM" in it (ie: nuvi 1490LM). If it has a "T" in the model name (ie: nuvi 1490T), it has Lifetime Traffic. If it is listed as "LMT" (nuvi 1490LMT) it has both Lifetime Maps and Lifetime Traffic.

I hope helps!

Maps for most GPS devices are updated several times a year. Your map is from 2010 and should be updated. You can go to the garmin site and pay to download and install upgraded maps or do a google search for map upgrades and you'll find some services offering lifetime upgrades for a few dollars more than the Garmin one time upgrade. I did this and have had no problems updating the maps on my Garmin Nuvi 250.

Do you have fix on the GPS?
Have you selected "find boat" and not "cursor" (bottom left button under the screen)? If you'r still stuck try a master reset (factory reset) by going into the menu and select system setup - factory reset.

Check the connectors and wiring between the GPS module and sonar unit. If it's an internal GPS module yo may have knocked loose a connector internally.

Try adjusting the GPS position offset in the GPS Sensor Settings Menu.

Hello:

I also have the Nautilus & the processor just isn't as fast as the newer units. You can adjust the track up mode to only refresh when the rotation of the map is over a cert amount, degrees, (resloution angle) if you have it set to a low value it will continually keep the route dead up & constantly refresh.

See section 4.3 Map orientation in the manual.

On the route reversal are you getting the pop up screen that alerts you that the route has been reversed?

I assume you have a manual?

I am actually contemplating selling my unit as I have a Garmin 478 from work & the screen is much easier to read in the bright sunlight. I had my Sitex on my Grady which had a bimini, but my Mako CC does not & the sunlight washes it out.

I'm thinking $375 for the whole unit with a wide area chart of MA.

Your manual tells you how to enter waypoints
