The touchscreen has become non responsive. Any ideas rather than take to the dealer? Thanks
Hi BrockT,
The procedure that [MENTION=143340]Skeptopotamus[/MENTION] is referring to is one that
RESETs the hard-drive/processor that controls the audio & Navigation systems. The theory is that this processor works much like
"Windows" operates your computer. Occasionally, your computer's registry/cashe gets bogged down with
"Temporary Files" "Idle Processes",...etc. Disconnecting power from the processor will clear the memory of these useless objects and reset the system to it's default setting; restoring it to it's original level of performance! To perform the navigation system 'Master Reset', open the main relay/fusebox under the hood.
4Runner's from 2010 to 2013 will have a fuse labeled
30A AMP. From 2014 and up, the fuse you're looking for will be labeled
20A RAD. Now pull the fuse that matches the description of the one that pertains to your vehicle and leave it out for a minimum of four hours; this will allow enough time for the the circuit's capacitors to drain. If you replace those fuses before the memory storage is fully drained the reset will not work and you'll need to start over!
PS: There's no need to pull any other radio or audio system related fuses as they are all de-energized when the vehicle is shut off!
cheers!
