Hi, the car now fitted with16:9 screen, BM54, MK4 DVD with v29. Originally the car was fitted with DSP,but after reading on this forum,getting it to work is a major job,so not connected at the moment.The X5 loom (2006) does not appear to have the DSP wiring,or rather a straight pnp fitment.I have a connection not used from the loom and will describe or take a pic of it to see if you guys could identify its function and will post tonight.Thanks again for the help.
