I have a 2014 Prius 4, sunroof, jbl system, etc. I'd like to replace the NAV/sound system with an Apple Play setup and am wondering if this will violate the warranty, and if it's a complicated replacement. I still have a bit more than a year to go on the 3 yr, 36,000 mile warranty. Also, is there a certain brand of replacement system, Sony/Panasonic, etc., that would work well in this car. Thanks!
