Does my furuno GP-32 need an external ground - Furuno GPS

The only place to get that screen is through a Furuno authorized dealer. The unit is sealed and gas filled to remain waterproof. You're best bet would be to send the unit in to Furuno for repair. You wont save much doing it yourself because the cost of the screen makes up most of the cost of the repair. They will also make sure that all the software is up to date for the new WAAS satellites that recently went on line.

Have you tried adjusting the contrast? On that model I believe you tap the power key while the unit is on and you will see 2 sliding scales on the screen, one for brightness and one for contrast. Up or down arrows select the scale and left or right arrows adjust it. If the contrast and brightmness aren't tied into the power key on that model, they're somewhere in the set up menu.

If adjusting the contrast doesn't help then the screen has most likely failed. This is commonly caused by old age, however repeated exposure to extreme heat or cold can cause premature failure.

Hi fire1961,

Downloading data from my FURUNO GP-30 gave me no problems. But it took me long time to figure out why I coudn't upload waypoints and routes to the GP-30 via the serial port in my ThinkPad T30.

I tried nearly everything tested the cable, tested a lot of different software and even wrote a little c-program to communicate with the serial port. I also tried a serial-to-usb converter with no results. Then I stumbled over this RS232 Tutorial. According to this - serial ports are not just serial port but can be divided into three general categories:

The types of driver ICs used in serial ports can be divided into three general categories:

* Drivers which require plus (+) and minus (-) voltage power supplies such as the 1488 series of interface integrated circuits. (Most desktop and tower PCs use this type of driver.)
* Low power drivers which require one +5 volt power supply. This type of driver has an internal charge pump for voltage conversion. (Many industrial microprocessor controls use this type of driver.)
* Low voltage (3.3 v) and low power drivers which meet the EIA-562 Standard. (Used on notebooks and laptops.)

Then I installed the waypoint upload software to my ten years old Compaq Presario and suddenly I could upload routes and waypoints but only via the on board serial port. The serial-to-usb converter didn't still work.

So if people experience no result trying to upload data to these old GP-30's from their notebooks and laptops. Then I think it could be a matter of these Low voltage ports not are able to provide the FURUNO device with enough voltage. See the above RS232 Tutorial.

Best Regards
