I don’t think anything exists any more, Alpine used to sell a complete replacement unit but last time they upgraded that system they didn’t include the VF-compatible one In the upgrade, and it’s NLA. I guess you might get lucky & find a retailer that still has 1yo+ stock, but it was a ~$3k unit.
The best you’ll be able to do is add a setup which can work on an aux input, and which can use CarPlay and/or Android Auto such that you can have SatNav software running on your ‘phone. Yeah it’s a bit kludgey, and the HUD functions will still use the existing system/maps/speed-limits, but other car functions will continue to work.
