Mark .buddy, why do you keep on calling the white section of the 40 pin plug the TV input? It's most confusing for everyone. When you had a pop at me and posted the drawing of the connector you were referring to, you had in fact pointed at the CD Input connections in to the BM54 unit in the boot. I had the same idea, bud, but from the other end of the car Yesterday I couldn't spell Engineer... Today I are one!

That diagram I posted was just one I found on the net, someone else put the lines on it. I was highlighting that the TV source in to the plug had left and right. I have always been talking about the plug that goes in the BM54 in the boot. It's where all the sources feed in. Some of the pins are tv input. Some are cd, some are tape....

Most range rover units need a firmware upgrade to enable aux mode, as well as the purpose made cable, with the correct resistors and capacitors. barisahan@gmail.com |

Not that I have much idea what you lot are talking about... but.... how will the volume control work, doesn't that come via canbus from the original head unit?? does it mean you have to go in the glovebox to turn it up?? Pete

Volume will come from the steering wheel, it will be as if you are playing a CD, and as the Android unit has programmable buttons, in theory, you should still be able to control it but leave the volume side to the CD, thus accessing the DSP!!

You can't program the buttons to do nothing on the Android unit, they come set from the factory and you can only change what they do.... Pete

Looks like the right combination of connectors will allow interface through cd connector then. Saves running loads of wires to the rear of the car as you say, but the aerial will still need to be run if you want to use those built into the car.

Seeing as most people opt to make their own aerial leads, I cannot foresee any problems with running a single coax from the boot to the dashboard , and then putting the connector on. With a bit of luck should be able to run underneath the threshold plates! Yesterday I couldn't spell Engineer... Today I are one!

Getting around the "B" pillar is the killer, the black plastic trim has no space at all under it, if it goes under the edge of the carpet it is bent through two right angles and is vulnerable to people in the back standing on it... it's only four bolts and a plug to remove the front seat and do the job properly, stripping it out until you have good access is not hard or time consuming...

Well, to be blunt, if you want it right, don't replace half an active system with half a passive system. You need to rip out all the bmw kit, including the speakers (which are not designed to work passively) and refit all new kit to go with the new android unit. There we go. No wire cutting needed, for those that want it simple. All things being equal, an active system will sound better than a passive system, so it's simpler but not as good. That's called a downgrade.

Dave, it would appear that you are attacking the problem from the other end, so to speak. I can see that by trying, and hopefully succeeding, to get all the door speakers to work properly, which is a worthy thing. I personally haven't got the time to construct, and try, passive crossover networks. When it has all been done actively buy BMW / LR. Plus I also get the feeling that the Nav Head does more than just adjust the clock, so I'd like to keep it. Doing away with as much troublesome components as possible, is an appealing idea, and to that end the DVD Nav head will be number 1 on my hit list, along with the TV tuner if possible, the CD changer has already gone!
