Hi Brad
Thanks for reaching out. With the LC ezCANs, we utilize the inputs from the handlebars, which amongst others include the Wonder Wheel commands. A few questions on your new navigation system:
Will the replace your existing wheel with another, or will the original remain but no longer interact with the navigation system?
If the former, depending on the new wheel, it might work as expected, as there are only 4 inputs that should be mimicked. If the latter, I suspect the wheel's communication to the navigation system will be disabled, but not the wheel itself, as you'll still need it to operate on board controls for your bike, which means the inputs will remain the same, allowing your normal use with the ezCAN.
On a side note, will this replacement be done by your BMW dealership?
Kind regards
Ruan
