Perhaps I can be of some help here.

LEAR is the OEM supplier BMW uses for the TV tuner. Other supplier for the TV tuner I believe were Philips, but that was sometime ago.

You may run into difficulties with the 4:3 only tuners and 16x9 displays. Over at bimmerboard A/V forum, some folks made a pretty comprehensive list of what tuners work with what displays.

The following information from bimmerboard NAV A/V forum

If you have a TV tuner, you can buy the original OEM retrofit wiring harness. Its just plug and play. You will find additioanl two wires on the harness that do need to be attached to the BM radio input (pins 11 and 12) for TV Tuner audio. Its very straightforward though.

Wiring harness part # (only available in Europe)

61-12-0-144-096 CABLE SET

For TV in motion, Dietz sell a TV in motion interface. Again very simple to install, and you can enable/disable it by using the Clock key on the NAV. Martin at bimmernav.com sell them.
