It all depends on what you like and can afford. I like the factory look as long as it sounds good enough. For me, I changed the speakers to the Mopar Kicker upgrades and the sound is plenty good for me. Good enough that I sold my Pioneer DVD touchscreen that I removed from my Chevy Colorado before trading it. I was planning on putting it in the Ram, but with all the extra stuff I would need and the factory radio sounding fine, I ditched the idea..
Also, I really like the Uconnect and ability to voice control my Ipod that's plugged in the glovebox. I wouldn't want to lose the Uconnect.
The only thing I might like at some point is to change to a touchscreen RBZ. I don't want NAV. I much prefer my navigation as a separate device.
