First post. New user. Been a frequent visitor. My 2015 hardrock has a 430n RHB radio. My trouble is that the touch screen does not work. Every hard button works. Every steering wheel button works. The screen displays everything. Voice command works. Shows the volume going up/down and changing of the channels but can not use the touchscreen. What is my problem? Is it the touch screen glass itself? Circuit board? Maybe the whole face unit? I dont think the whole radio is bad nor do i believe it is the hard drive to which i may be wrong. Im just looking for help. Sorry if this exact situation has been discussed already just havent seen it discussed to this specific problem.
