Everything thing from Bose is coming separately, the rear speakers are installed now just waiting for the sub.
Also upgraded to a Garmin RV 890, fantastic big screen but had to devise a no drill mount for the dash. It comes with two mounts, a suction cup and a screw down mount. I made an acrylic plate to bolt to the bottom of the screw down mount so I could use 3M VHB tape to attach it. The screen attaches to the mount magnetically.
