nope.
It's on the bus to listen for vehicle speed so the active volume can go up and down. Advanced one spit out channel and RDS data for the HUD. there is zero possibility to send out a "lock up the breaks" command from the car stereo into the CANBUS unless you rewrite the stereo's firmware first. and that is not gonna happen, There are a LOT of guys looking to hack GM and Ford satnav systems to get past the damn CANBUS VIN lock. They have had ZERO success in the past 5 years.
Ive been working on this for the past couple of months, and I have had success.
(Search for VE Commodore HVAC Radio Hacking on google).
Simply grap a SOP Clip, and an EEPROM programmer.
The VIN number is stored as plain text on the Radio, Cluster, BCM, and a few other modules....
The main reason why Manufacturers have been integrating the radio in to the vehicle, is because the radio is no longer just a radio, its an info/tainment center.
HVAC controls, Sat-Nav, Park Assist, Reverse camera, radio, Bluetooth Audio connectivity, Video in Motion prevention, etc....
On GM vehicles, there are two separate buses, the high speed GM LAN, which is used for critical stuff such as engine, transmission, brakes, stability management, etc....
Then there is the low speed BUS which is used for stuff like HVAC, Radio, Instrument Cluster, Body Electronics, etc.
What the article is trying to point out is that FORD for example, uses wifi to program its Ford SYNC (Windows CE) system at the factory.
Whether a wifi module is plugged in on the line, and removed later is anyones guess. However, all the Low speed (Non critical stuff) is usually accessible via the low speed can bus, such as locking/unlocking doors, and remote starting of the car (via the Body Electronics Modules) etc.....
