first thing I yanked out was that archaic oem radio, maestro rr and a couple more adapters to retain rse + new headunit (of your choosing) and you are golden
I retained the bose amp and all rse function plus gained front video, wireless android and carplay, modern navigation, added sub's & amp.
if you shop around used on ebay you can do it for under 1k. headunits are priced up right now because of the chip shortage like vehicles but used ones show up for a better price
a used maestro rr is no big deal because they get flashed by usb to your vehicle anyway so it doesn't matter if it is used or not they can be flashed over and over for any use.
