Thanks.

I used the same instructions and mine works perfectly. Which connectors are you using? On my E60, it would turn off and on if I hit a hard bump because the connector didn't have a snug fit.

What issue are you having?

Almost guarantee one of your connections isn't secure.

I'm using hardwire connectors that came with the v1. plug everything in, turn car fully on and I get no power in unit. how can I test connectors? I'm thinking goto RadioShack tomorrow and get volt meter to make sure the green brown wire has the right voltage. what external 12 volt source can I use to test connectors?

I figure I'll also get new wiring harness connector too.

Assuming you tapped into the correct wires, as Bish said the issue is a bad connection. The blue tap connector that comes with the V1 is for 14 - 18 guage wire. The OP in the installation guide used red tap connectors that are for 16 - 22 gauge wire. The wires you tap into in the overhead console seem to be either 18 or 20 gauge. To utilize the blue tap connector you need to take extra care that you get through the wire casing so the connector can make good contact. I also used blue tap connectors and to assure a tight connection I did two things:
1. Use needle nose pliers to squeeze the metal "U" the tap connector that the wire in the overhead console will slide into. Making it a little bit narrower will help the connector cut through the wire casing.
2. Once you snap the connector shut, gently slide it back and forth on the wire.

Try these two things and see if you can get it to work.

Echo the above comments and especially check your ground connection. In my E39 and E60 hardwires, I grounded to one of the screws on the sunroof motor.

Seems the green-brown wire in this area has consistently been the ticket for power over the model years, IIRC.....
I need to do this mod soon to get rid of dangling wires...

I did the same on my E39 and E60 M5s, however I couldn't get any of the sunroof screws to work when I hard wired into the F10. Had to use the wire as described in he step-by-step instructions quoted above.

praise the gods! I finally got it to work! thanks for the helpful suggestions. I did need a narrower connector and grounding is needed after all.
