I'm wondering....might it have been easier to just reconstruct the entire car from scratch?

My car also has a combox in the boot and so I think I will use your provided method here for all wiring job. However, there is a point I'm still not clear.

Regarding the wire jump of pin13 to pin15 (step 31 of your guide), I actually need to close the loop of NBT end of the extension harness or the other end?

Could you help me out?

Many thanks!

The wire jump was performed on the Extension harness end where it connects to the head unit.

Thank you for your quick response!
I understand that wire jump was performed on the extension harness at the head unit end. I have created a diagram of this situation. Is there any chance you can help me have a quick look and confirm?

Appreciate your help.

You're welcome. Here's a rough representation of the wire jump.

Great! You help me out already!

Another quick question. I have combox at the back and I have HiFi sound system. The wire jump is used to transfer signal back for the case we need to put combox offline? Apart from knowing what to do, I also want to learn more.

Really appreciated.

Hello, I have a question, in the car I have the bussines CIC, my question is that if I can install the screen of the CIC professional to him. Someone has proved it and it him has worked?

thanks

The wire jump was used to relay the audio signal back to the speakers for those with Hi-Fi. Not, 100% sure on why the combox needs to be offline, I was advised by my coder to remove it. I think by placing it offline, it will bypass the validation for non-genuine activation codes.

Theoretically it should work. I think you can swap out the LCD display and connect it to the existing head unit via the Magenta cable. Not sure if it's the same cable or output rate though, so there's a chance it might not be compatible. Might need to confirm with your seller or installer if it's compatible.

Hi knightsabers,

When I rewire the MIC cable last night, after I detached the MIC cover and try to pull out the old MIC cable, I found it is quite hard to do so. The room underneath the headliner is so small and I'm just afraid breaking the little wire of the MIC.

Will you advise to use something, like screwdriver, to extend the room underneath the headliner while I pull out the wire? Is the old MIC cable coming from the center location instead of the direction of windscreen so that I need to pull in the right direction from center to side door?

Thanks in advance!

Yeah, there's very little room to maneuver between the headliner & airbag. I fed the cable from the center console to the 'drivers' side center console, removed the plastic grommet and doors seals. I then taped the cable & mic to a bent clothes hanger and 'slowly/gently' weaved through till I reached the speaker hole. Then it's a matter of pulling it out and plugging in the mic cap.

Hi knightsabers,

Using a bent cloth hanger is really a good idea. I will have a try later.

What you are talking is about wiring the new MIC cable. However, I'm still at stuck the step of detaching the old original MIC cable plug near the speaker hole...

I need to pull the old original MIC cable out a little bit from the hole first before I can see and detach the plug. I think this action of pulling out original MIC cable is very hard because of little room. I will try using a screwdriver to expand the room and pull out the original MIC cable a little bit until I can detach the plug then go to the step you mentioned.

Thanks a lot, man!

Hello, thank you for answering, I think that if it was working, the bad thing is that the resolution of the screen are different and it is possible that so one sees good,
I asked if someone has proved it, Sure that someone has done

[kitster]

Just as a heads up, the ProNav screen will not work when connected to HU_ENTRY (non-nav head unit), the cables ends are different. The non-nav cable is burgundy at both ends. The pro-nav cable is pink and burgundy; even with correct cable the pro-nav screen remains blank.

[zyxel]

Thank you very much, it is what was waiting for me, better then the change to nbt professional

[zyxel]

But I have the busines,s the alone change is from the screen of the CIC businnes to the screen of the professional CIC

Hi knightsabers,

As what mentioned above your car is coming with Combox in the trunk, same as mine. May I know is there any antenna installed in the shark fin on top of the car?

I found my car seems to have antenna in the shark fin and I can't put the aftermarket GPS antenna there. Strange....

I've just completed NBT retrofit as well. Your write up helps me a lot. Thanks again!

You're welcome, glad it could help. As I had 'Business Nav', previously so mine was fitted with the antenna in the Shark fin.

Here's an example what it should look like.

Just checked the realoem.com, my car is really having the antenna but is one not for GPS purpose

If I need to install BMW GPS antenna, I need to cut the the fin cover, which is so scary...I give up....

Very nice install guide you have. May I know where did you get the USB converter, the White one? I understand that the CIC connector is not a direct fit.

It does seem like a bit of a task to remove the cover. I know there's a shop in HK, Pasco-HK that installs NBT & other parts. Might want to check out how much they charge to install it.

I got the converter & the entire kit from a seller in Singapore, Elebest who shipped it over via Express Post.
