this one serves no practical purpose and is just an exercise in laying wires...

I realized i watched that AV video twice now haha, it seemed very familiar before i realized it too late.


ANyway.. Before you sell your car please let me know!!

item 44 on the first page

started some prep work for the mirror fold-in on engine shut-off...

I don't really like doing splicing unless i absolutely have no other choice, so I have built a Y-splitter for the door modules... So, with this splitters in place, I will have to bring in the power feed from the relay bank, that was already prepared earlier... On the relay bank, the black is ground, red is +12VDC, green is power-on-LAN (in original design, that wire would be the ignition voltage). Two pins on the central relay that are NOT soldered yet are the ones that will provide the voltage to the mirrors...

still, the hard part is to figure out the transfer of wires from the door to the main body of the car - it turns out that the boot connecting the door to the car does not have wires simply traversing from the door to the car (as in the boots in the trunk lid) - there is a connector, I think it is listed as a 30-pin connector, with not all of the pins utilized, some pin locations have no pins, so I might be able to pin them

As always, very impressive!

After I installed the AUX, and did my BT setup for the streaming music, the system developed alternator whine. I spent little time troubleshooting the problem, with so many things happening at the same time, but was able to determine that the whine was not induced in the audio cables running next to power cables, but rather was introduced directly from the power supplies that operated the BT dongle and the phone - as I would connect a "clean" power source, not part of the car, the whine was totally gone...

I tried to filter the whine, even built a custom filter but the amplitude was attenuated only a little bit, not enough to consider a success...

after digging a bit deeper, I found two (!) cold solder joints that disconnected on me and the setup lost proper grounding - one was in the ground wire itself, and the other one was in the right channel...

Once those two cold solder spots were fixed, there is no more whine...

On to something next on the list...

Wow!!!

No wonder, airlines don't like lithium batteries, this one looks like it's pregnant!!!

Best way is to snap the battery completely off and remove it fron the device, having it powered by the power supply/ adapter. The BT dongle works fine without the battery, with a 5V supply.
I am not using this particular dongle in the car (i have dongle with slide power switch for the car), but was using this one at home until the plastic shell popped open...

Your thread is always an inspiration for this particular X5 owner Term. Thanks for posting you project progressions. I need to start a similar thread for mine as I usually do this sort of thing for all my cars as a nice reference for to what has been done... yeah my memory sucks.

Anyway, that was a long winded way of saying thanks.
