By chance I have just come across a Land Rover accessory for the RRS Mk1 caller TrailAir and it appears to be a kit for a camera and TPMS for the trailer.

It looks like the same idea to help hitch up but it may display on the mirror? Anyone seen such an accessory?

Edit: just found a YouTube vid



Could it be this device running through an Aux in on the surround camera? Is the video in the OPs video even showing a RRS Mk1 screen? 2012 5.0 SC AB

Have seen these advertised before, typical overpriced £500.00 bit of kit from L/R. Looks like they may have integrated similar sort of thing in later surround camera system, not sure about the TPMS side though.
