I've got a 2011 limited with the jbl navigation and I don't really care for it. I've got a 2013 bezel and an android radio that I might install. I see examples of replacing the jbl system while keeping the stock navigation unit. I also find people replacing head units, but none replacing the navigation head unit. I would prefer to keep the jbl amp and sub, but if I have to replace the whole system I'm fine with that. Has anyone replaced a navigation head unit or the entire jbl system? Any tips would be appreciated. I don't need a steering wheel adapter or backup camera adapter. I have the stuff to handle that part already. Thanks for any help.
