Brand new owner of a 2015 Cruze LTZ with the RS Package. Best I can tell it has most every option but the Navigation. Is it possiable to add this and if so, what would I need. I've seen the correct radio head on eBay, but is more needed..? I thought I've read here that Chevy will not provide the software if the car did not come original with the system. Any help out there..? On a side note I learned that my Cousin works at the plant that made the car on the Dash Install Team. I've had the car about two months and really love it.
