I was driving around the other day and wass shot by laser on 93 luckily my blinder went off and saved my a$$ but my X50 was silent....I've never had it go silent when I wass hit by laser. I have it on the mode where there is a small H on the left hand side and a dot scans across the screen. When I Looked at the X50 I saw that the dot waqsn't moving at all. I turned the detector off and then back on and during its start up mode it froze on "blue". It seems to be working fine now but I'm a little worried its going to freeze without me noticing. Has this ever happened to anyone? Any way to prevent / fix this?
