Help ! Any suggestions appreciated.

[Airfiddler]

I have a Zumo 350 LM which has suddenly started acting up. The touchscreen is now VERY unresponsive. I have tried reloading the maps...no change. I have taken out the memory card and rebooted....no change. The onboard memory is not full (about 60%) I have held down the off button untill the unit recycles up to four times, to see if I can get a hard reset.....no change. Generally the screen may respond after 10 to 12 touches, but then its locked up again, arragh !! I have had this unit since new, so it is well past warranty. Can the firmware/software be reinstalled ? There is no physical damage to the unit, I suspect a software bug somewhere, does the touchscreen wear out ? Is this unit worth sending in for repair ? It was not inexpensive and I feel I should get more than 5 years use out of it, as it was not abused, or damaged. Thanks for any advise on this frustrating situation.

Welcome to the Forum Airfiddler, hope you find it friendly and helpful. If I could suggest [mention]Stu[/mention] could move this topic to the specific Z 350 section, you may get more views and hopefully some help. Cheers, Pete.

first i would check and make sure nothing is lodged around the perimeter and stuck touching the screen and then look to calibrate the screen.

This really sounds like a failure of the touchscreen. It does happen. If you haven't received any 350 specific tips regarding resetting the device or recalibrating the device, I would recommend that you contact Palm Doctor, Shortronics Inc. www.palmdr.com. They're a small company that does out of warranty repairs on GPS devices along with other smart electronics. I've used them to repair a Zumo 450 and to replace the touchscreen in a StreetPilot 2610 (if you can believe that those are still running). Repairs on both of my GPSs were reasonable and pretty quick. There's a page on the web site to request a repair quote.

I'm not sure from your comments whether you've done a proper master reset but before you try any hardware repairs try a master reset. That often cures issues like this.

I rather doubt he waited around for 5 months for more advice.

didn't look at the dates

Any one still using these and having issues?
I know I am and the hard reset does not work on mine.

How are you performing the hard reset ?

Update.
Took it apart, cleaned screen terminal connection and removed and replaced battery connection.
All good except after updating maps it says "can't unlock maps".
Frustrating.
