Hi Rawad
As you posted in the firmware thread:
I purchased my model before the announced release and was lucky to have gotten the hardware, however I purchased my tech package for 3750 which means I didn't pay the extra 500$. I was told I would get it for free after the release and have yet to see anything yet.
Because your order was placed before the autopilot announcement, your car has the original "tech package" not the "tech package with autopilot"
All original Australian delivered orders were in the same situation because we ordered in May/June 2014 and received delivery starting December 2014
We were offered to "upgrade" our tech package by paying the difference, if required.
Parking sensors and fog lights are included in the new tech package, so if parking sensors were ordered the upgrade was free, and as I had ordered both parking sensors and fog lights I got an AUD$600 refund.
In my case the car hadn't been built yet - but my impression is that it's a "software switch" so it can be upgraded after the fact.
I do not know why cars with tech package and autopilot hardware were not all automatically "upgraded"
I suggest that you follow up with the person that told you the upgrade would be free, and find out if they can upgrade you to the "tech package with autopilot"
