The MG iSMART app (v3.5 or newer) now supports recurring departure times. You can set weekdays for cabin preconditioning (heating/cooling) and battery preconditioning – a crucial feature for winter range preservation. This relies on the R24 update syncing with MG’s backend servers.

  • Issue: USB music library resets every time the car starts.
  • Issue: Range estimate dropped by 10-15 miles immediately after update.
