run a new constant 12V from the battery. some have this issue, others don't. not sure why. just had to do that last night to an e92 head unit install we did 2 weeks ago. car had 12V constant at the harness for the 10 minutes i held the test light there with the doors all shut but i guess after a few hours it timed out.

Fuse box or battery. I don't remember having to do that to my car, though. 12V constant is in my harness.

Try switching the red and the orange cable (I suppose you should have it) so it looks like: Red cable->Orange cable and Orange cable -> Red cable. (On the harness between the car and the HU.
It solved problems for me earlier, latest when installing my parrot MKI 9200 |

That is strange although I guess it is possible since the headunit is turned on and off by the CAN signal. The connects2 harness is not wired like this it has a seperate lead for constant 12 volt so I ran it to the battery.

I also found this on my nav hu. I am going to swap red and yellow pwr wires to see if that works. Logic tells me that this worked on head unit and that did not lose its memory.

Hi
Can you confirm which fuse you plugged in to? I have the Connects2 kit and need to plug my yellow 12v into the fuse box. But it doesn’t state which? Kind Regards |

Test it on a bench to make sure. You can use the CAS fuse to power it as CAS must always be on. |

I have had to connect both the red and yellow (live and switched live I Think) into the live connection and connected the live 12v feed to fuse 83 which was empty in the UK version 2008 fusebox. This does keep the memory but also doesn't switch the HU off so I have to manually Switch it off. Thanks |

I replaced my old Sony CD Player with a Mechless Pioneer HU with bluetooth. I ran the 12v switched live to Fuse #2 and connected the red-red and yellow-yellow on the harness. The memory is fine and the cd player only turns on when the key is in the car woich saves me having to remember to turn the CD player off like with the Sony HU.
Thanks to all for the advice. |

Having sorted this problem out today, if anyone is reading and has an 07 E92, my fuse #2 was unused and I connected the 12v yellow wire into that using a fuse-tap/piggyback and a 10amp fuse.
I have tested the unit a few times since (after waiting over an hour to ensure the car was asleep) and my new android unit has retained memory and started up fast rather than going through the initial boot phase. So it looks as thought fuse #2 is an unused permanent live on 07 E92 models. |

This is all really good info. I installed a new Alpine double-din and ended up running a power cable back to the battery. I really like the fuse trick - easier than running a cable to the trunk!
