iBUS installation location

I have mk4 nav and dsp so every thing is located in the trunk.

Getting ready to install my avin 4 and looking at Reslser's install wiki page it does not recommend installing it behind the dash where the connectors are for the screen.

It recommends tapping right by the Quadralock farka harness. Which then would require me to get a USB extension cable BUT it doesn't recommend using any extensiona either.

Says something about certain functions will not be able to communicate.

Wiki page: https://wiki.ibus-app.de/index.php?t...-USB-Interface

This is a catch 22 lol

Anyone who had mk4 nav, where did you tap in your iBUS and how well is it working?

I thought about doing this, but once it mentioned having to buy an 6M extension since I have navigation that I would have to run the length of the vehicle just for it to work - I decided against it. I am not about to gut the interior to upgrade my head unit. It's just not plug & play if you have standard navigation from factory. One perk of business radio is that it's easy to upgrade to aftermarket head units as they are truly plug & play. I believe all 4.8iS came standard with navigation?

I have this issue with my 2002 M3 as well since it came with navigation. I desperately want a modern head unit or at least BT for that matter in my M3 but it's just not possible without gutting. I could go FM transmitters (which blow) or GROMM which is probably my best option without taking out the interior. I have already retrofit aux with wireless BT in my 4.8iS and i'll just leave it as-is.

That sucks! I was just about to install using the old monitor cables. That page was recently updated as when I originally read those instructions there were no notes about missing data using connections other than the radio adapter. I do not want to pull the interior again... I'll check the TIS and see if there is a bus line at the LCM...

Edit: If you are worried about USB extensions, as they recommend against... just extend the wires on the iBus interface to wherever you decide to install.

What would be the difference between extending the ibus wires vs the USB end? Really baffled.

Yeh lots of red flags with that. The connection should work anywhere on the bus if the protocol is handled properly which I don't think it is by the sounds of it. Putting it in the back probably adds some delay that by chance/luck band-aids some data conflict/collision and allows it to work better. Definitely would be a good thing for to hear about some other peoples experience with this.

You ordered the avant 4 right? Mine came with a pigtail off the main harness for the iBus USB

Shouldn't be any. But they recommend no USB extensions. They don't say you can not extend the input wires. Unless I missed that somewhere.

Yes but my harness will be at the trunk so I want to confirm if I should extend the wires or get a USB extension.

USB extension being the easier option.

If your iBus adaptor and harness are in the rear, why not use the CD changer 3 pin connector? It has the 12V, GND and iBus already there.

He will be in the same situation of extending the USB interface with a USB extension cable. Personally, I'd rather extend the original signal iBus wire than the "interpreted" signals via a USB extension.

Remember. All that no extension stuff could be a CYA policy as well. Same thing with having to tap in the rear at the radio harness. I tend to agree with 80stech that this is a coding issue rather than an issue of where you are tapping the signal from. Just my thoughts though as I have done no testing or trial/error to test that.
