Question about Lowrance iWAY 250C GPS Receiver

1 Answer

Touch screen failure

My 250c got misted with water, not soaked but enough to evidently cause damage. I opened it and found no evidence of moisture, but left it open over a light bulb to thoroughly drive out condensation. Unfortunately it boots up to the warning screen and that's it. The touch screen won't let you x it out. Is there any hope? I liked this unit, would be a shame to pitch it.

Sometimes it pays to procrastinate. My 250c gps was left in a drawer for a year and a half as I hesitated to pitch it. I turned it on recently and everything works good as new. The battery was still fully charged! It must have dried out over time.

5500 Navman no brightness selection


Its water ingress causing a short in the high voltage wiring PCB.

Open the unit with a 1.5mm allen key, unscrew the power/data cable sockets with a spanner and GPS antenna inlet with an 8mm socket (no antenna socket on i models) .

Where water has arced there will be burning black on the green PCB evident, cut the gold PCB flat wire and remove the section around the burn.
scrape a small amount of green off the gold flat PCB wire so you can solder a new wire to bypass the short. any 2.5mm insulated wire will do to bridge the gap you have just scraped away, there is plenty of room for a 1 inch wire.
Dry the unit and seal with silicone to prevent re occurrence.

Its a 2 hour repair requiring a high DIY soldering standard but off set it against the time it will take to reload you waypoints in a new plotter , its well worth the trouble.

Touch screen quit working Nuvi 660 hasnt been dropped or wet battery fully charged, anything you touch on the screen doesnt go there


This is a common problem caused by a hardware failure of the touchscreen. It needs to be replaced. More info can be found here:

Suspected moisture in Furuno GPS/Plotter display


You need to determine if it's moisture or damage to the protective coating on the LCD glass. If the screen coating is damaged it will have patches or discoloration that resemble water spots like you see on windows and glasses exposed to hard water. If it's moisture between the glass and LCD you should be able to make out the tiny water droplets that are evenly spread throughout the screen. The only proper fix for a glass with damage to the protective coating is replacement of the bezel assembly. If it's moisture you can try inserting a few silica gel packs inside the unit. Don't try to disassemble the bezel (LCD/Screen) assembly. Just but the gel packs inside the 1650 chassis and give it a day or two. Otherwise, you're looking at factory repaire.

The touch screen now works intermitantly, and it appears that their is a mist on the inside (water??). No one has opened this unit up. Is it warrenteed? What is the fix for this?


It sounds as if a small amount of water or moisture has entered the GPS.

The 2730 is now a discontinued product, and if bought new, is likely out of warranty. If purchased recently (less than a year) as a factory refurbished device, it would normally be covered under a Garmin Factory warranty. Water damage however, may not be covered.

If it is no longer covered, Garmin offers a "flat rate" repair for $170. Learn how to go about obtaining this service at the site below:

http://www8.garmin.com/support/warranty.html

A couple things come to mind... at $170, to me - it doesn't seem to make much sense to repair, when "like new" factory refurbished GPS units can be had for the same / less money. The refurbs come with 1 year warranties (instead of a 90 day type after repair) & latest version of maps.

Lastly, if you don't want to do either of the suggestions above, you could attempt removing the back cover and allowing the device to fully dry out in direct sunlight for a day or two. Reassemble and operate the GPS again. Doing this sooner rather than later will increase the chances of successful drying with having permanent water damage.

Good luck!

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.
