Replacing sat/nav radio with aftermarket question

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.

Thanks!
Matt

If you end up doing this and are interested in selling the OEM head unit PM me and let me know what you would sell it for. I am in the market for one and I am in the Dallas area as well.

have you looked at Crutchfield? You can use their "what fits my car?" wizard to find out what is compatible.

Crutchfield is rarely the cheapest price, but with free shipping, free install kits, and free tech support for life, there are worse deals out there.

I am more concerned about the canbus system, which isn't really cleared up (for me at least) by crutchfield's website or the countless forum posts I've read.

I don't want to shell out $1k for a head unit and several hundred for an amp just to find out some canbus adapter cable is going to limit the head unit's features (fading, EQ, etc).

So is unplugging the stock head unit and not usin ghte amp going to hose up the canbus?

Rustynail, not sure if I will sell it or not. I kinda like the idea of having the stock components available to put the car back at stock for when I want to sell or trade in the car. This is my third jeep I've owned consecutively, so I kinda see where the future leads if they ever put out one with, say, a hemi or something.

Run new wires from the speakers to the JL amp, it might take a little bit of time (although it's not too bad a job compared to trying to run new wires in a little Jap compact) but it will be worth it. The existing wiring runs through the factory amp and if you try to keep that inline then you will run into CANbus issues, because the HU and the factory amp use CANbus to control functions such as fade.

Use the PAC RP4-CH11 harness to wire into the vehicle wiring, but leave the speaker cables from the vehicle disconnected on the harness. This way you'll still get all your switched power, ground, SWC etc connected into the new set up, but sound output will go from the pre-outs directly to the JL amp and over the fresh wiring to your Polks. No CANbus, no problem.
