In a website announcement:
…Tesla all but announced the much anticipated update for older cars with MCU1 (generally, pre-2018).
Those with FSD pre-purchased will get priority for the upgrade, and the implication is that Tesla will install the AP3 computer at the same visit to service. It’s priced at $2500 in the US, so pricing and availability in Australia is a little bit of an unknown.
TOCWA asked the Perth service centre, and they said:
“Currently limited to US only at this time. Other regions to be announced. Until its announced for Australia, there’s no point booking in.”
