I decided to keep the factory headunit and upgrade the speakers and add a small Kicker Key 180 amp. That seemed to do the trick as my sound is incredibly better. I personally didn't need Apple CarPlay, although it's damn cool, and use nav on my phone vs the Entune nav, so the stock headunit, although underpowered, was fine.
Living near the #1 auto theft/break in city in the nation also prompted me to keep things as stock looking as possible...
