Yea so i bought a 2010 with a nav system, but with after market kicker speakers and bose sub, if you want to replace sub also that could be done. its not a super difficult to do, what you need is a summing processor which takes signal from wires that run to bose amp in the back and gives you rca out puts which you can then run to after market amp and whatever speakers you want. if that is not clear enough let me know...i can take some pics of my truck set up. Also if you want to mess with frequencies you can add a sound processor between summing processor and amp.

if you want to remove nav, you can do that by replacing it with base model ac controls, then you can add an after market head unit, amp and speakers
