Touch screen stop working

I've been thru 3 Omnitech GPS systems. The first problem was the touch screen stop working 3 weeks after I had it. Took it back to Staples and exchanged it. 3 weeks after that, the touchscreen stop woking also. So I took it back AGAIN and got another one, this time a month later it lost the signal and kept searching for it even though it said it was getting a good signal. I took it back Staples gave me a refund and the manager said he wasn't selling it anymore because of to many issues with the device. It is garbage for sure.

Hello,
Omnitech GPS systems are very decent for me. I have 2.
There were several reports of GPS problems beginning on or about 11-14 June 2009. This is due to the GPS navigation messages rollover from 255 to 0. Some GPS systems fail to accommodate this behavior; Omnitech is one of them.
Staples did provide a firmware update a few days later. There are also other firmware updates available on the net. I personally successfully update the firmware and resolve the problem around June 15, 2009.
Otherwise, the problem should go away after 1-2 weeks.

Please do NOT attempt to make this repair -
You may or may not permanently damage your GPS device!

I got my OmniTech GPS from Staples late August 09.
Everything works fine at room temperature 70 degree F and below.
I realized that when I put the GPS in my car (Las Vegas at 100-110F outside), the touch screen stopped working at high temp. So I put it in front of the air condition vent of my car - and viola -
the touch screen came up again, and worked fine.
My conclusion: some tensions (expansion due to heat) must prevent the touch screen from doing its job.

So I took the GPS apart (4 little screws in the back+2 screws on the Printed Circuit Board inside). Disconnect the battery and the
speaker (unplug the connectors). The touch screen is fastened by
4 plastic snap-in hooks (or anchors or fasteners). I noticed that the
top (2) hooks are pretty tight. When I tried to wiggle the screen
out of those hooks I broke the 2 upper (top) fasteners (hooks).

No worries, the back touch screen pushes against some kind of
anti-static foam on the PCB, and the PCB is fastened by 2 hooks
and 2 screws.

I put GPS device together, except for the broken hooks.
The touch screen works fine now, at temp 110F and above.
No more problem with the touch screen.

I had this problem about my touch screen same with you. The touch screen on left hand has stopped working. I had it for 20 months. I live in Thailand. I think that it is the big problem for ST550. I've brought it to Samsung Customer Center. and they've introduced me to change the new touch screen. It is about USD50.00. I am bored. I used it a little bit.

Nuvi 650 touch screen stopped working


My Garmin Nuvi 650 would boot up and load maps, but I could not enter my access code. Screen would not respond. Turned off & on a number of times, but still same problem. This occurred on first use after upgrading the maps. Thinking it may have overheated on the dashboard of my truck, I held the device in front of the air conditioner vent for about five minutes to cool it down. When I then turned it on, it worked fine. For the rest of my 3-week vacation, I kept it cool & out of the sun when it was not turned on. No problems after that.

Omnitech GPS 16878


  • Try to press and hold the power button for 15 sec when the unit is off
  • then when the gps on check if it will go thru but if it is not try to press the reset button for 10 sec and then release.
  • if still not work try to charge the battery sometimes the cause of the freezing of the screen is when the unit is low in battery and also check the website if there is a new firmware for your gps if there is download it.
