Motorhome TV Connectivity

Armanello12

I would be very grateful if anyone could steer me in the right direction with TV connection.  Very recently purchased a used Elddis Sunseeker 200 motorhome and as a 'newbe' trying to work out how things work!!

Would welcome any advice on the TV connectivity available in the van?

Have taken a couple of photos of the sockets/ports available to me but unsure how it all works together.  Would be particularly interested in purchasing Avtex Pro 12v compact TV package?

If any one could steer me in the right direction in terms of necessary adapters etc that would be much appreciated.

Regards

Chris
