Question about Garmin Edge 305 GPS Receiver

1 Answer

My display screen during the ride will sometimes go blank. Then I cut it back on, but also have to hit "START" again. Display shows all accurately, but last 4 rides or so when I upload informtion to my computer, it give inaccurate average speed! I usually only avg. 17-18, and it had read anywhere from 22-29 for my avg. speed, which definitely is not correct. What can I do? Do I need to ship it back to you? I have had it less than a year, but it was a gift, so I will have to track down receipt, if still available! HELP!!!!!!!!!!!!!11

Right I've just fixed mine, after somebody stated the obvious and suggested I check the contrast. It was at absolute zero... I turned it up... problem solved. I dont know if this will fix yours but give it a go and see.

Hi Todd, My internet was down, so I apologize for not getting back to you sooner. unfortunately I have never worked on that model and I am not familiar with it. I mainly work on car-based units. Does it operate off of batteries? If so, are the batteries fully charged? Is there any chance of a bad connection between the power source and the unit? Is there a master reset for the device? Since I am not familiar with this unit, I would not be right to receive any payment from you. - Jim

Device: Garmin Nuvi 660 NA. After power on, nuvi boots thru to the "Where to" page. On the prior page, the touchscreen will not click "Enter" but after a time delay, nuvi proceeds to...


*Master reset your Garmin Device:


1.Start with the unit OFF and unplugged from power;

2.Touch and hold the lower right corner of the screen with an index finger or the eraser end of a pencil

3.Continue touching and holding the lower right hand corner of the screen then power the unit ON

4.Release the power button when the device powers ON

5.You will see a new message: Do you really want to erase all user data?

6.Remove your finger from the touchscreen when this message displays - Touch Yes

7.The device will automatically reset. Please follow the on screen prompts on the nuvi .


*If the touchscreen is incorrectly detecting where your finger touches the screen, the screen may need to be calibrated.


1.Power the unit On.From the Where to? and View map screen, touch Settings . Touch Display>Touch Re-calibrate


2.A new screen will display that says Press Dot,Touch the Center of the Dot.

>Keep touching the center of the dot as it moves around the screen.


3.When Calibration Complete appears on the screen, please touch OK.

The screen will now be Re-calibrated.



*If the screen is not responding to touch, the device may not have enough power to function properly. Recharge the battery completely and try again. If the battery does not charge, it may need to be replaced.

If the screen is still not responding to touch commands or displaying properly, the display may need to be replaced. If sound comes from the device, it is likely the motherboard is working, and only the display needs to be replaced.

Refer to:Garmin Nuvi 660 Screen Replacement Guide

Before replacing the display, check that the ribbon cables connecting the display to the motherboard are connected securely.

I recognize the problem. It mostly occurs when the plotter is exposed to moist during some days. The contactstrip which connects the computer to the screen gets moist and does not conduct in an optimal way. The result is a non readable screen with stripes

The solution is simple: press on the edges of the screen and the contact is re-established.

White oval spot in center of screen on garmin 2720 gps


The touch screen is made up of several layers. A thin plastic layer, a micro thin metal layer, microdots for insulators, another thin metal layer, and a final plastic layer. All of these layers amount to the thickness of a sheet of paper. This whole stack is bonded to a thin sheet of glass and placed over the actual TFT display.

If the touch screen is still working the moisture probably isn't between the layers. My guess is moisture got through one of the gaskets and made it's way in between the touch screen assembly and the TFT display.

If you want to clean it:
Remove the six screw holding the case together.
Split the cases and pull the patch antenna out of it's slot.
Remove the four silver screws holding the display assembly into the front bezel.
Unhook the small ribbon cable that goes to the infrared receiver under the red lens.
Pull the display assembly out of the front bezel. It won't come all the way out because of cables.
Use a razor to cut the plastic tape holding the touch screen bracket to the TFT display.
Unlatch the 4 conductor ribbon connector nestled between the 2 big white wires.
Use a penknife to unbend the metal tabs keeping the touch screen from coming loose. I usually just do the ones by the IR receiver.

Now that the touch screen is in your hand you can carefully clean the moisture from between the two assemblies. The gaskets are tricky to install again but it can be done, maybe you'll see where they were leaking.

With the charts page up, start by hitting the find ship softkey at the bottom of the screen.If that find the boat on the chart all is good.If not you need to check you have a GPS fix. Go to GPS screen and see you are seeing satalites.
If all is good when you hit find ship and the boat disappears again from chart while underway you will need to go into the chart setup menu and see if the screen amplifier is turned off. If off turn on.This is first place to start. Hope that helps

Screen goes blank


Maybe the setting of your video display was change to higher setting, and your screen cannot handle the said setting.

When a "safe mode" message appears during opeing, select that options, then at the desktop right click your mouse, chose properties, then setting, then change the screen resolution to lower range.
