E53 wiring diagram?
 

Hi guys

I am trying to locate a wiring diagram for an 06 E53 with nav.

I have an aftermarket radio and having trouble wiring the power and earth connections correctly.

I have the 2 small connections, one blue and one white.

I need the constant power for memory, switched power, and ground wires please. I have tested the ports with my multimeter, but the wires I have used give me switched power only unless I ground to the body, then I get constant power even without the key......

Thanks in advance guys

Thank you for your prompt response.

I'm a bit dopey I guess, and can't tell where to.fond what colour wires are what on their diagrams...... Sorry......

Thanks again

Have you realised that with nav the radio module with all audio connectors is in the trunk?

Yes and I have the patch cable coming, but I'm not sure whether the patch cable does all the power connection as well?
Xtrons won't respond cos my head unit isn't a current model.....

I installed an Xtrons into one of my X5 with NAV. Unless your car's wiring was cut previously it should be a plug and play installation with the long (patch) cable going from back to the front - quite a bit of fiddling to get it concealed properly..remove a lot of trim and front passenger seat. Just string the long cable over the seats to test first.

Look at the wiring diagrams if you want to, but I wouldn't do anything until you get that patch cable.
