Hello to all. I am posting this because I feel there are others out there with touchscreen problems and are having a very hard time finding someone to repair them.
I want to share my experience with all on the replacement of my Magellan 3250 NA GPS touchscreen.
Our Magellan started having issues about a year ago with low battery life and an occasional shift of the touchscreen's position.
One day the touchscreen shifted 1/2 inch high. We could not get to the calibration screen because the buttons needed were on the bottom and each touch was too high.
Since the battery was getting old, we thought it may be heat (it was summer) or a faulty battery creating heat and resistance. After seeing a video on 3250 battery replacement we replaced the battery feeling afterwards it was fixed. Sure enough it seemed to not give any more troubles.
This shifting of touch placement happened again months later. Totally letting the Magellan go dead and repeated attempts to restart to assure it was dead was done. We then plugged in the Magellan to charge and afterwards it was OK.
Again a few months after that, now about a year after battery replacement, the screen went off 1/2 inch again. This time no trick used would correct it. We then decided to replace the touchscreen.
We found a used Magellan online that looked visually good, and appeared to have little use (no scratches) and bought that for parts. The battery replacement video mentioned before showed how to open the GPS. Remembering that we used small fine "Watch Screwdriver Set", thin plastic pry tool, or fingernail, and gently opened the Magellan. The screen is right there and the ribbon cable is taped to the back plate to prevent it from slipping out.
CAREFULLY peel back the sticky tape away from the back plate and the connector. Once done you see a black connector and white "seat" it appears to be in. Here is the trick. The connector does NOT come out. The two white ends (tabs), or what looks like the "seat" of the plug moves upward and downwards 1/16th an inch. These two white tabs compress the copper ribbon inside the black plastic "plug". By moving the white tabs down it released the compression on the copper ribbon and it comes out. We took the screen from the parts Magellan we purchased and replace the whole screen assembly into the old Magellan we had been using for years, pushed the white tabs back "closed" and pressed the tape against the back plate and reassembled the unit.
It worked! Now our old trusty Magellan 3250 is working again.
I wanted to post this for anyone contemplating repairing a GPS touchscreen, particularly the Magellan 3250.
I hope someone finds this useful.
Congratulations on a successful repair! Most folks would have just thrown it in the trash. Out of curiosity, why did you repair your old unit instead of just using the used device you bought for parts? Was the used device also not functional?
Thank you for reading and the congrats.
The Magellan purchased was nonfunctional and only for parts. Besides we want *our* Magellan not another person's property or problem.
I was very saddened by the lack of support out there and wanted to put something back to the, internet Magellan world.
Now, if some programmer or developer would make a *how to* on cleaning up, refreshing or doing some form of maintenance on the Magellan with its Windows CE that would be nice. Similar to the Windows Desktop, are there any temporary files to discard, any old error logs, or other items to keep the Magellan OS running smoothly.
Hi all, here is some more information on trying to maintain your Magellan GPS. Since Magellan is using Windows CE, I thought it may be good to run some of the Windows Desktop programs such as Microsoft Disk Cleanup and Error Checking (AKA Scandisk or CHKDSK).
I plugged the Magellan 3250 into the USB port on the desktop using older XP and then opened Windows Explorer. Right clicked on the Magellan's drive letter and clicked on the TOOLs tab. In there I checked the drive for errors. It said the drive was in use and had to schedule for the next reboot. I rebooted but it must had thought the Magellan plugged into the USB port was a boot-able device and it hung at the black screen with a non flashing cursor. I turned off the Magellan and pressed reset on the computer and when it went past the BIOS screen and started loading Windows, I turned on the Magellan. After a few seconds the Windows start screen changed to the blue screen stating the drive was going to be checked. CHKDSK checked the drive and it did hang on some of the percent done numbers like 1% or 6%, but it did make it through to the finish eventually. I was surprised to see it found some drive errors and corrected them. Upon finishing the drive's error checking I ran Disk Cleanup. It found some strange leftover, System Restore: Obsolete Data Storage files and I allowed Disk Cleanup to remove them. I did the same procedure to another Magellan 3250 we had and it went without any hangs (it does stay at 6% for a while then jumps to 70%, 83%, 90%, 95% then counted upwards to 100%) and it did not find any errors on that particular Magellan.
I did run Disk Defragmenter on a secondary Magellan we had. It looked to be about 60% fragmented, but it only defragmented the two blue halves and put them together. The rest of the drive remained fragmented. No real success there. One person on the internet said his Magellan GPS was slow so he copied all the files to his computer's hard drive, formatted the GPS, then copied the files and folders back, but in a specific order... so he said. I am not sure of the order at this time, but copying back files that would make them contiguous and may speed things up. Furthermore the formatting of the GPS drive would reveal and deal with any bad sectors (although running Disk Error Checking does this too). Here is a site that another poster said to Defragment and still another said a copy, format and copy back helped them. http://forums.gpsreview.net/discussion/24682/roadmate-2136t-...
Another item I would like to mention is a found Boot Time Screen. If you hold down the internal Reset button, and turn on the Magellan at the same time, a boot screen appears. Be careful! I did not open or adjust anything there. I looked at it then hit the Reset button to reboot the Magellan. I did not want to ruin anything by experimenting.
Hope this helps others.
