Have a 2013 Prius whose Screen became unresponsive a while back.. Radio and bluetooth were working when I could get to the controls... Had bought a OEM used unit (57032 dash id) to replace a couple years ago but could not find the time or shop to get it replaced, and the box was sitting in my garage. When I went to a dealership this week, asked them if they would replace the unit for me and they did. However, now it appears to have gotten worse in that the Apps button does not work, and neither does Bluetooth ... Would the unit not being used for a while in the garage cause it to go bad? Also, am thinking of getting another unit from eBay to replace this faulty one. Any advice/recommendations from the experienced owners here on the next steps? Do not need a fancy system, since the OEM unit if working with Nav/Bluetooth/Audio would suffice for me for the next few years before replacing the car.
