While I cant speak from personal knowledge, my guess is this:

The movement of the pin is the key. It probably doesn't ACTUALLY matter which pin you move to the new location, only that you have A pin there (it just so happens that the MUTE pin is nearby and not very useful).

As to the specialness of the new location, I suspect it is placed there as 1 of 2 things:

1) A developer debugging tool, that is left in the final design.

2) An intentional 'for the customer' bypass for use in non-car application (e.g. in the back seat of a motorhome, or in a boat).

I would bet dollars to donuts that using the bypass has literally 0 harmful effect on the navi accuracy of the system.

Which mute function are you talking about?

Can you press mute? Yes.

Can the BTB100/200 mute the unit? yes

Can an external device mute the unit (like a Parrot BT adapter)? No.

Yup. It rebooted the system, and compained about the wire again. Though I'm not sure that the reset did all THAT much, as it didn't reset the 3D calibration settings at all.

Double check your connections. You need the pin to be firmly set into the new hole in the harness and you need a good ground for that wire and the parking brake wire

I am very experienced with soldering and moving pins around connections. I am 100% sure that I connected them properly, and that they remain connected properly, as my multimeter shows basically no resistance through those pins.

Okay the bypass works for me too.

 

Only thing is, now my car disables the controls if the car is in motion. After driving about a 1/4 mile I got a screen from the unit saying it detected that the parking brake wire was improperly disconnected. Then I noticed the navi search controls were disabled. The second I stopped at a traffic light they came back and then as soon as I started moving again they went away again.

 

Hi,

I'm having the same issue. What was your ultimate fix to get it working? Thank you in advance,

Elliott

I got the same issue as well. I am 100% sure that the mute wire was moved to the right location and that it as well as the PB wire are grounded properly (confirmed using my multimeter).

I did everything for the bypass (moved the mute wire, and grounded the parking brake) and it worked for the first 2 hours of my drive up to Santa Rosa. However, on the way back it reported that the Parking Brake is connected wrong and started disabling the functions it doesnt want me to have in motion.

Ideas?
