Navigational (global Positioning System) Gps problems of the 2019 Subaru Legacy

The radio, which is also impacts screen, is defective. It is available for examination. The radio jumps stations with beeps, the sound can’t be eliminated by turning down the volume. It indiscriminately jumps from satellite to fm. It will hold a station for a while but then it jumps around. I get a few seconds of a music or talk station and then it jumps. It is a safety hazard since the beeps distracts the driver. It doesn’t recognize applecarplay that is used for gps navigation. The screen when it manages to show the menu, does not respond to touch so you can’t use gps or access other vehicle processes such as clock, brightness, etc. I can’t use the phone for navigation while charging only seeing turn-by-turn directions, no map. The dealer has ordered a replacement radio but it is back ordered. The vehicle has not been inspected by anyone other than dan perkins Subaru in milford, CT. No warning indicator, it just started exhibiting the jump problem. The experience started gradually and would go back to working order. It got worse over several months, first appearing 7 months ago. Internet search shows this is an issue with several Subaru models and years.
