Should be labeled but its in the picture of the fuse board
in entry 32 (06 fuse diagram pdf.) The missing fuse might be part of the bystable relay failure. Last edited by ctuna; 02-18-2019 at 06:16 PM.. |

f2 diverstiy antenna fuse you might note that
when you get past your current problems. Looks like you will have to look around for a new Nav. |

If you want to DIY a kit you would need a CIC, screen, cic trim, display cable, usb cable, usb port, display power connector, coding and most likely an emulator to activate the donor FSC to your car. You can reuse the factory CCC knob with the CIC which is what my kits do. I linked the BMW Fanatic video earlier which he installed one of my early kits. |

If it was me I would take those final measurements I asked
you to take. 12 volts at the radio connector and checking the fuse on the back of the unit. If those check out about the only thing you can do is try another unit. The fact that the radio lit up kind of says it must be getting power with fuse 23 in but I don't know why because the description of that fuse is for modules that are normally in the Trunk. Although you might try to run diags with all the fuses in place and the radio/nav disconnected. I would also want to know if the 30g relay is any good. Relay could be bad of there may be burnt traces on the cabin fuse board or other component damage there. It would also be advisable to get K/D can cable and set up the INpa suite and Ista D they are much more powerful diagnositcs than Carly. You will need the Inpa suite to program a new CCC unit or whatever you deciede to put in to your car if its OEM. It would be a good idea to establish if you have Hi Fi or Logic 7 sound system and amplifier to. If you buy Nikco43's kit see if he can pre program it for your cars options. Seems like the person who sold you that car was withholding info if you didn't know about the missing fuses. Last edited by ctuna; 02-19-2019 at 01:39 PM.. |

Good idea if you want to do it.
He said he found +12 on pin 15 of the radio connector so it should power up. Since he has an 06 there should be no ICOM issues. I keep hearing that cars with dcan need icom for most module progamming . somehthing do with the speed of dcan but the exact reasons seem nebulous. Last edited by ctuna; 02-19-2019 at 07:04 PM.. |

What do you mean by running?
Do you mean it won't go to sleep or that it works? And how would you tell if it was running with no lights or screen?(DVD noise?) (Should go to sleep after a minute or two with the doors locked I get it.) power to the radio connector and doesn't work looks like a new unit or repairing an verifiing the old one is the next step. |

All kinds of things can stop the car from sleeping.
If the cars senses doors are open trunk is open having Comfort Access (No key required for operation ,and the key fob in the vicinity of the car ) ,leaving the radio on paired cell phone in the vicnity of the car. Leaving a comfort access key to close to the car. Locking the car is suppose to make it go to sleep faster. Descriptions of how this works is in first electrical pdf supplied earlier in the this thread. See entry 8 first pdf Also this https://www.google.com/url?sa=t&rct=...4WC0kufqupC_b3 Last edited by ctuna; 02-19-2019 at 09:33 PM.. |

All that means it it has two positions that routes
things either one way or the other. at least that is my understanding of of it. https://www.newtis.info/tisv2/a/en/e...ariant/XBybvmN Last edited by ctuna; 02-19-2019 at 09:54 PM.. |
