As stated a few days ago, I did my 8.4 update to 18.45.01. All went super smooth, so I thought. Fast forward a few days and the Nav update I bought from HERE cam in and I decided to go for it yesterday.
Problem: Can't get the update request code when plugging in the USB drive from HERE. Crap...... Come to find out, the USB hub in the console is now dead, after doing the software update on the radio. This is odd, I thought. Checked fuses, rebooted the infotainment, yada, yada, yada. Nothing. Pulled the hub out and disconnected wiring and restarted truck. Turned off truck and reconnected hub. Bingo..
All works OK now. Maybe it was the software / firmware update, maybe it wasn't. Who the F**** knows, but it works now.
Nav update went as planned after that.
