Hello everyone,

My 2014 is250 radio started acting up, so I took it apart to find that 2 plugs are unused behind it. I'm wondering what are those for since on most youtube videos, I see that only the brown one is unused, while I have also the white one on the left.

As far as the radio, it reboots sometimes while other times it just stays shut down completly for X amount of time, then boot back up after a few days.

No other choices than a new headunit apparently, but I have a canadian model with nav( P10435 ), can I interchange it with a USA model by buying a new sd card? If so, which model should I look for?
Thank you ​​​​​​​
