Yes all the CIU have that built into them we used to have a forum member here that would be able to clear all of this up. I keep in touch with him matter of fact he no longer works for Fisker which is very unfortunate . He took over the job of getting the CIU back on track
I'm here...
To clear it all up, all Fisker CIUs are equipped with the hardware and software for both Nav and Backup camera. It is through a software coding that enable/disable those 2 functions. This is how it is done in most automotive companies to save cost.
Only Fisker tools can enable or disable these functions.
The only real difference in hardware is between the European units and North American units, and this is due to Sat Radio Receiver.
About the compass:
The Fisker Karma does NOT have digital compass onboard. It utilizes GPS reception to calculate headings.
It also has accelerometer/gyroscope inside of the CIU that performs dead-reckoning algorithm when the GPS reception is lost. This is evident if you drive the Karma into a parking structure, you'll lose GPS reception, but you will see the navigation still tracks the vehicle's heading (at least for a while until the error accumulates too far).
