Very good question by Rocketmahn. The ONLY hardwire connection I see from the TV adapter that can support a FW upgrade is the micro USB port being used to power the TV adapter. But maybe there’s a wireless connection between the TV Adapter and the FittingLink, too, I just don’t know? Although almost all FW upgrades I’ve seen done in the past with any electronic devices have been via a hardwire.
I asked my audi about getting the TV Adapter FW upgrade done at the same visit I’ll be having for the OPN FW upgrade and she said sure, we can do both at the same time. But I don’t really know if she actually knows what needs to be done for the TV Adapter yet, or she was just saying OK and worry about it later.
