Trying to install a new Carplay hub but before that I need to update from FW 59.xx to 70.xx with current hub however it seems like my current media hub is dead . Here's how I know:
- Center console USBs do not play media from phone or read USB for FW update (FAT32 formatted), HOWEVER it does charge my iPhone with specific cable.
- DTC Error: B125287 (USB Port 1-Missing Message)
- Took apart dash and USB cable that runs from media hub to CMU wasn't loose or any visible damage.
- Did continuity test using a multimeter on the pins of that ^ USB cable, it passed, all pins working, cable works.
- Only thing left is the USB media hub and the CMU/driver issue, I would think the media hub is the issue given CMU works fine for everything else.
Did I miss any other diagnosis?
If it is the media hub, can I just buy one off eBay and swap it out then update CMU to 70.xx without an issue (non-apple carplay ones with only 1 plug in the back)? Or is it more complicated than that (say it has to be exact model and on exact FW as my current hub?)
