This upgrade works for any land rover vehicle including discovery with the dvd player pictured above to allow users to cast their phone to their land rover screens inside the car. 
 
It is demonstrated on the l322 but will also work on l320 , lr3 , discovery etc. providing the dvd player is the same as the one pictured above which they usually are. any indescrepancies i will work with you on them in order to have it work or it may be returned. 
 
This upgrade simply replaces the DVD player in the back compartment with its 3 connections. no cutting, soldering or splicing required, it just plugs right in with no issues.
