So its been bothering me for a few weeks since the winter sneak peak of FSD. Do I have a HW3 FSD ready PC in my model 3? Well some said if I can see cones I do , Some said 2.5 has cones as well. I decided to check my actual computer in the car to see the serial number and match it to the HW3 serial on the tesla parts website. To do this you 1.remove four plugs under the glovebox 2.pull out the panel 3. stick a camera up into the space facing the front of the car 4. review the footage to see what the serial number is. HW2.5 SERIAL: CAR,COMPUTER,MCU,ADAS,ASSY, HW2.5-PROVISIONED 1098058-S0-M HW3 SERIAL: TLA,CAR.COMP,NA,HW3.0,M3 - PROVISIONED 1462554-S0-I Tesla Parts Online: https://epc.tesla.com/#/systemGroups/47362 Hope this helps! Have made a video as well if preferred.
