I will be upgrading from an 02' Camry to a 2015 WRX come next Monday, and have been scowering the DIY thread here (2015 WRX & STI Epic Thread of Knowledge - NASIOC) for information on replacing the factory headunit(am looking to put in a single-din Pioneer DEH-80PRS. From what I've been hearing is the stock unit is at the very least, not good. The thread I linked above had most of what I needed such as speaker size, what wiring harnesses to get and how to uninstall the factory unit. However, I still have some questions that hopefully someone can help me find answers to:
1) How will I get Bluetooth integration/steering controls to work with the new radio? Is that something the wiring harness addresses? Or do I need to do something more customized?
2) Will the change in wRMS output of the new radio affect the stock speakers negatively? Are the stock speakers too sensitive for the Pioneer DEH-80PRS?
b) Also does anyone have specs on the stock headunit, if the headunit is 4v, and the PRS is 5v is that a big deal?
Thank you in advance!
