I am sorry if the answer to this question is summed up somewhere, but most sound/head unit upgrades seem to address the non-navigation factory head units.
I have a 2012 JKU Rubicon with premium sound and satelite navigation mygig radio.
I am wanting to replace the head unit and amp with the following aftermarket equipment:
Kenwood Excelon DNX890HD
JL Audio XD700/5
(or something similar, likely marine grade)
I do not want to use line convertors.
I do want to retain steering wheel controls.
Do I just disconnect the old head unit and physical connections to the speakers (which are already changed out to Polks)?
How do I install the aftermarket head unit and amp without screwing up the canbus system.
The only headache I want to risk is from having the volume turned up too high.
