Hi all, wondering if I buy the tv tuner from eBay the Land Rover that’s supplied from new but they sell on eBay for like 75 quid:

Is it a case of just taking the multimedia dash apart and plugging it in, then connecting it to the antenna on a split ? And the tv function would program itself into the menu or something.

Seems too easy and too good to be true but just wondering if I buy one will this work, anyone know of this being done ?

Have attached a picture of the unit.
