Has anyone done any aftermarket stereo and/or speaker/woofer upgrades in their ZR2?

What did you go with? The infotainment in these trucks suck! Never connects to my phone, gotta reconnect every single time, Sirius XM never picks up and plays without going either a channel up or a channel down to get it to start playing. Seems like the latest OTR made it even worse.
I’m curious to know what others have done to their ZR2

The forum search function is your friend...a lot of stereo upgrades on this forum...mostly speakers and subs. There is no good way to change out the head unit based on how it's integrated.
