I am new to this site. I have a 250 that is two years old. After start up the menu screen comes up but then locks. While driving eventually the map of my location comes up but I am unable to enter any "where to"s". I went and updated the software at Garmin but that did not help. I tried resetting and nothing Any suggestions?
Do you have an SD card in it? If so, try removing it and see what happens.
Go tools- settings- security(scroll down)- open security and turn safe mode off
I was thinking screen-frozen lock, not safe mode lock.
I cannot open tools for that screen is locked.
I'm not sure if this helps but on my 265WT, sliding the power switch to the right locks the screen.
Yes the 250 does the same thing
When I power on my 250 the menu screen freezes not allowing any touch screen commends to work, like the operating software does not completely load. It will not allow me to reset either. I have tried the rest button behind the sn sticker but all that does is turn it off. I have tried pushing in various corners of the screen on start up with no luck. When driving, eventually the map showing where you are comes up but will not allow the touch screen to do anything. I have done a software update on the internet but no change. When I plug in the usb cable the green bar on the start up screen only goes about 3/4ths of the way across. Maybe this means it is not allowing a full software start up when loading? Maybe I should let the battery completely run down and then recharge and see if that does anything. I am about ready to toss it in the trash. I was hoping someone else had experienced this and knew how to fix. The unit is two years old. The clock keeps perfect time. The screen is nice and bright and beeps on start up then freezes.
Before you follow the advice given to you below, did you check to see if any POI files you added could be the source of your problems?
It's possible your firmware update was corrupted. Try loading an older version of the firmware from http://gawisp.com/perry/nuvi/ .
The file you download is a self-extracting zip file. Make sure your GPS is connected to the computer and turned on, then run the firmware file. Once done, disconnect from the computer and let the firmware update.
Run your GPS for a short while with the older firmware to see if the screen freezes up again. If it does freeze, then by a simple process of elimination (eliminating software issues) we can conclude that the screen's digitizer is failing. While you can get the screen replaced, it's easier to replace the unit. You'll get updated features such as text to speech and speed limits, along with updated maps.
I tried each of the 250 updates one at a time. None of them fixed the screen freeze problem. Like you said maybe the screen's digitizer has gone bad.
Unfortunately, it's time to junk your old unit and get something new. A nuvi 255 is the current version of your 250. I'd personally go with the widescreen version, but that's a matter of taste. In any event, you'll get the following benefits from getting a new unit:
* Screen redraws much faster due to faster processor.
* Speed Limit indicator (US only).
* Spoken street names.
* QWERTY keyboard (the 250 had an alphabetical keyboard that through editing a file could be made into a near QWERTY keyboard).
The one thing you lose on changing units is the banner bar at the top displaying the upcoming cross street when you're not having the GPS guide you somewhere.
