I got an RCD330G+ from china (aliexpress) a couple months back for £150. Straight swap, though you have to update canbus gateway if you have an older one. Includes Bluetooth, apple car play, android auto, handsfree mic etc etc all integrated into the unit. And its OEM equipment from the China/Russia/India market, so VW logo on start up, dims when lights turn on and volume alters with speed.
Go for "revision E" to make sure all works as it should! Earlier revisions are even cheaper but have some niggles.
