Comand NTG2.5 (MY09->MY12)
The (optional) factory tuner is different between each version of the system, and there is no digital tuner for the 1st version. so if you do have the 1st version with analogue tuner the best option is to add a digital tuner connected to the AUX in on the analogue tuner.
The official antenna are in the front windscreen, but you can not install the antenna amplifiers without removing the dash, so if you don't have TV tuner already in reality you will have to put stick-on-windscreen antenna.
