Hi guys. So Tesla on their website have used (off lease) S models available for sale. When i go to check out there is NO option to upgrade to FSD computer at all. It just goes to payment option. I believe from what i've read here upgrade price to FSD would be $3k? Tesla (Enhanced) Autopilot vs. Full Self-Driving: What's the difference now? So few questions 1. How does one upgrade that to FSD threw tesla website? Are those AP1 only for sale or AP2 as well? 2. How does one know what version of AP tesla website sells? It's not really listed in specs. No cameras numbers either. 3. How does one upgrade to FSD if i buy threw private that has AP bought already. I'm assuming that's again $3k upgrade? I've seen one very few with EAP and that actually costs more to upgrade then AP version, a $1k more based on the link above. 4. Does EAP have 8 cameras correct and what version of HW (2.0 or 2.5) is EAP? Can you clarify all this for me as this is very confusing at least for me. Many thanks in advance. I'm looking to buy used Tesla S that is capable to upgrade to FSD, meaning has full suite capable of just module swap.
