I'm new to the forum and I'm trying to post a question. I hope this is in the right place. My 2006 Prius' touchscreen has stopped working...Only way to get info is to use the on-steering-wheel controls. The toyota dealer said it needs to be replaced and it will cost $1800! That's like buying a new imac. Is there anyother way to get this repaired? Help! I've loved my Prius (which I got second hand last year) but if this is the repair costs attached I might as well trade in for a Ford hybrid. Any advice would be appreciated.
