Do you have a friend on the mainland in either SF or LA? Having them pull one of these off a Prius at a wrecker and mailing or bringing it to you is going to be the best way to do this in terms of price.
Question do I need the whole display or can I just replace the screen inside of it like I've seen for sale on eBay?
It's less work/less hassle to get the whole display with the plastic around it... Main thing is getting one that matches your vehicle as some are equipped for GPS and some are not. Also the screens that handle the back up camera are much higher resolution than screens that don't.
