okay so it appears now that i am having simliar issue...
it started last weekend with the inability to use the hard keys on the bottom nor the touch screen.... but it would fade in/out... after a while i would be able to, but then it would almost go immediately back to being inoperable.,.. Stuff like the map screen just shooting off in a westward direction all by itself... and/or when trying to enter an address it would select various numbers or selections all by itself... kinda like someone was touching the screen.
At any rate, now i am at the point where there is an address in the GPS which i can not cancel, and that is awfully annoying.... and cant do anything but change volume...
NOW in full discloser, i have had the Z1 for apprx 3 years and havent had this issue until this past weekend...
SO is this firmware the fix i need? and how do i install? just burn onto disk and load into player?
maybe i should look at the link provided... going there now... in lieu of that, any help/input/suggestions/confirmation(s) are appreciated.
pls thx
matt
