Beginner Question, what does this get you over stock?
I ask because I am in the market for a 06+ 4th gen 4runner. While the JBL is nice, most of the used ones I'm finding don't have it. So lets say I have a stock 06+ radio. I already plan to get a $100 Garmin, and probably a pro.fit mount ($60). I never considered an aftermarket head unit, but I'm already spending $160 on a nav system so might as well see what another $300 will do (seems like they are going for ~$500 on the FRS forums w/ the nav unit.)
Obviously it has a snazzy touchscreen interface, and the nav would be more integrated than a portable Garmin. It has Bluetooth to phone. It has HD radio, which stock does not have, right? Can it play DVD movies? I really don't care for internet apps or anything else I could just use my phone for. It doesn't seem to be worth it for me, but again I'm pretty ignorant as to what these aftermarket units can do.
