So for those who might be following this, the file that Eric M has sent me (24 bit 192kHz) that plays fine in his car does not play in mine. I get the same loading error as my other 24 bit files (96 khz)
But he has a spanking new car, with an MCU2 of course, and mine is an MCU1. Not sure about the OP;
@Zepman which media unit do you have? or what is the age of your car?
I did call Tesla and the first person I talked to said he wasn't aware of the issue. He checked my vehicle on his end and all looked fine, he suggested I remove the usb and any chargers and do a power off as well as a reboot. (standard response) I did that and no difference.
I called back and spoke to someone different who
was aware of the lack of playability of hi-resolution files. She put more notes down and sent it off for someone to read and hopefully it will be deemed important enough to solve the coding issue on a future update; preferably the next one.
So if anyone is having the same issue I encourage you to call and report the issue; the more comments the more likely the the fix will come; squeaky wheel gets the grease so to speak.
