Zumo 550 Screen "Twitchy"


Recommended Posts


My Zumo 550 is about 1 1/2 years old. I noticed the screen was "jumpy", and gave inconsistent results to touch. I put some mild water and detergent on the screen, then using the edge of a dampened busines card to keep from scratching anything, I cleaned the tiny gap between the screen and the case. Then gently rinsed / wiped with a sponge.


Voila! Screen problem solved, and did not have to re-calibrate.


Thanks to Zumo Forums!
