I have an '04 Prius package 9 (NAV) with 77K miles & the screen appears to have a loose connection. Radio come & goes at its discretion; NAV sometimes works.; INFO is a hit or miss. Dealer says need a new screen-$4000. Out of warranty. 2 years old & an electical malfunction???? Toyota must have bought them from Sony. 2 years & 1 month til it failed. Anyone else having this problem? Any suggestions?
