1. DEVICE DESCRIPTION
General Motors’ (“GM”) Vehicle Cockpit Unit (VCU) 1.0 is a technology upgrade for the previous
generation GM Cockpit ECU platform (“Info 3.x”).
The GM Vehicle Cockpit System (“VCS”) is responsible for the user experience in the cockpit of GM
vehicles.
The VCU, a Bosch device for GM vehicles, is a silver box solution providing interfaces to displays,
speakers, sensors and optional components of the VCS.
The VCU, provides the following capabilities:
1 Vehicle and infotainment related information to the slim-IPC, ICS, auxiliary, HVAC, and HUD
displays. This includes processing of various vehicle camera viewing streams to certain displays.
2 Audio capability that includes processing various radio broadcasts to the vehicle, voice capturing
using microphone inputs, user media playback via phone or USB, and integrating audio
enhancements (for example ANC) using microphone inputs.
3 Wi-Fi, Bluetooth, and GPS connectivity.
4 Various analog and digital I/O, including but not limited to switches, HUDs, sensors, etc.
It supports two major GM electrical vehicle architectures (called “Global B” and “CLEA”) and is offered in
two major product variants: “MID” and “HIGH”. In terms of regional support, a distinction is made between
North America (“NA”), China (“CN”) and RestOfWorld (“RoW”) configurations.
The VCU hardware is based on a two-processor approach where Qualcomm’s latest ARM-based
automotive system-on-chip (SoC) family 8195 (High) and 8155 (Mid) acts as core computing element and
Renesas Electronics' latest automotive micro-controller RH850F1KM/KH (Vehicle Interface Processor, VIP)
is used for real-time processing needs.
The VCU software architecture is mainly based on 3 run-time environments (called SW domains):
• Running on VIP:
o AUTOSAR OS as real-time processing system
• Running on SoC:
o Blackberry Hypervisor V2.x based on QNX7.x to realize a host environment and guest
environment as virtual machine
o Host: QNX7.x operating system
o Guest: Android system based on Linux kernel
The VCU can determine its geographical location:
• In the VCUNM1 the positioning information is provided by an external device, the Telematics
Module.

2. SAFETY AND WARNING NOTES
This paragraph contains important safety and warning notes for handling and operating the device in
series applications.
• The product is intended, and has been approved, for installation and operation in vehicles with a
rated voltage of 12 volts. It may be necessary to adapt the product's factory-set state to suit the
specific country.
• Only connecting cables and external devices that are appropriate for the device in question may
be used (e.g.: proper current carrying capability, proper EMC shielding, flammability verified with
appropriate certificates). Compliance with the applicable standards can no longer be guaranteed
if the device – including the software – is modified without the agreement of Bosch.
• Bosch assumes no responsibility for damage as a result of incorrect indicators/displays. These
may arise if the device has not been connected or has been incorrectly connected, or if the
device receives false or erroneous signals from the system.
• Do not cover ventilation openings and heat sinks. Otherwise, a build-up of heat that could lead to
malfunction may occur in the device.
• Do not insert foreign bodies into the insertion slots or openings of the device. Injury, or damage to
the device, may occur otherwise.
• The device must not come into contact with hot or burning objects (e.g. cigarettes).
• Never use hard or sharp objects that could scratch or damage the protective pane or housing to
clean the device. Do not use aggressive cleaning agents such as thinners, gasoline, abrasive
cleaners, spray cleaners, acidic or alkaline solutions, or wax. Do not spray any liquids onto the
device. To clean the housing, moisten a soft cloth with tepid water and wipe off the dirt. Make
sure that no liquid enters the inside of the device. Afterwards, wipe the cleaned surface with a
clean, dry cloth.
• The housing/surface of the VCU may be very hot when the device is operational. Please exercise
caution and use appropriate protective equipment (PPE).
