HW3.0 - Secondary Radar?

Tesla leaks new self-driving Autopilot hardware 3.0 computer diagram ahead of launch

Looks like the retrofit may be more than just a new computer given there is a secondary radar input for HW 3.0

Nope- AP2.5 had that too

Can anybody confirm if (and when) Tesla changed to Continental AG as their radar supplier? Was it Bosch before? What's the scoop? : teslamotors

Tesla changed the radar to Continental with AP2.5. Yes, the AP1.0/2.0 radar was made by Bosch. The information was found in Autopilot code here. The new radar is expected to have better range. Interestingly, the code also shows that the new radar has two sets of wiring, one called primary and the other secondary wiring.

I would assume this is some of the "extra redundancy" they mentioned was part of 2.5- the radar being so important to the system for safety- and 3.0 just carries that over.
