My touch screen stops working after a few hours of use. It begins a slow decent by first sticking on a key or a scroll bar and goes south from there until the entire screen stops working. The Navigator button still works as do the other buttons on there but the touch pad is completely dead.
The fix is to completely wipe out the memory on the device and resync but since this happens SO OFTEN it is a HUGE annoyance.

Re: Touch Screen Problems
You may want to use the Task Switcher that you can start by going to Settings/System. When you click on Task Switcher, you will see all of the open programs. If you have a large number of open programs then you may see a degredation in performance. You may also have a single application that is causing problems. If a soft reset cures the problem, then it is not a hardware problem.

That happened to me and my htc touch hd the other day. I tuned it off, pulled the battery out and let it dry out completely. The touch screen didn't work until a few hours later. However when water happens to an electronic device it usually will need to be replaced. Just cross your fingers and hope for the best.
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.
The touch screen wont register if the unit has been reset and sometimes when it updates. Use the side buttons to control the cursor. Click the menu button, and then use the down arrow key to slect settings.click settings with the ok button. use the down arrow button to scroll down to display. click ok. The display screen will come up. Use the down arrow key to go to touch screen calibration. Use the ok button to select this option and follow the instructions. You will have to use the stylus to tap three calibration points on the touch screen and it should work fine from there.
To determine if there is an issue with the touch screen, you need to follow these steps:- * Turn on the unit and select any user. * Select 'Option' from the keypad. * Then select 'Configuration'. * Scroll down to select 'Diagnostics”. * Scroll down again and select 'Touch Screen Test”. If you can complete the 'Touch Screen Test ', it implies that there is no issue with the touch screen. The most effective way to use the touch screen is to select using the tip of the finger or with a blunt end of a pen or a stylus. However, if you cannot complete the touch screen test, it would imply that there is a problem with the touch screen.
