I have recently completed my NAV Mod on my Lexus IS 250 to cater for rear headrest entertainment system. I have two A/V input sources now available on my NAV screen using standard RCA cables. I have setup a Double DVB-T tuner for the first A/V input and the second A/V input has been plugged into a SlimLine PS2 with wireless Controller Pads. This is all viewable on the SatNav screen aswell as simultaneously shown on the rear headrests.

The headrests also receive DVD Video Playback from Nav DVD Unit, which has also been hacked to provide DVD playback on the move.

I have taken a brief video on my camera phone showing the reception and quality of the DVB tuner which was tuned into BBC News 24. Reception has been tested on speeds upto 75mph with excellent reception and with no picture loss. However built up areas can affect reception.
