Since MCU2 doesn't support AM radio, upgrading from MCU1 to MCU2 was likely going to lose AM radio - and because many AM stations now have HD Radio channels on FM, that's OK.
But if the MCU1 to MCU2 upgrade also loses FM and XM, that is unacceptable, because using the apps provided by Tesla there isn't a replacement for accessing live sports and news using streaming apps (at least not so far).
If this upgrade is going to be required in order for MCU1/AP2/FSD vehicles to get access to the new FSD functionality, then this is completely unacceptable - unless Tesla provides an alternative to FM/XM that provides comparable access to local and national live sports and news (equivalent streaming app or screen mirroring access to equivalent smartphone apps).
If MCU2 provides FM/XM - why can't MCU1 vehicles continue to get those radios?
If not, Tesla should provide an alternative to those owners unwilling to lose FM/XM radio.
Providing a refund of the FSD purchase isn't sufficient, because the decision purchase was likely influenced by Tesla's claim at that time that all vehicles had hardware capable of FSD.
We might be willing to consider trading in our 2017 S 100D for a new S/X with MCU2, the latest AP hardware and FM/XM radio - if Tesla transferred FSD/FUSC/extended warranty to the new vehicle, and because they are saving resources and costs by not performing the MCU2/AP3 hardware upgrade on a 3 year old vehicle, they should also include a $5000-$10000 trade-in credit.
How could Tesla believe dropping all radio from vehicles would be acceptable right now (without any alternative)?
