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 is a silver box solution providing interfaces to displays, speakers, sensors and optional components of the VCS.

The VCU, provides the following capabilities: · 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. · 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. · Wi-Fi, Bluetooth, and GPS connectivity. · 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 VCUNH1 the positioning information is provided by an external device, the Telematics Module.

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).

OPERATING MODES AND WIRELESS CHARACTERISTICS
Bluetooth and WiFi can work together. The device operates with two Antennas (one internal and one external Antenna). Bluetooth signals are sent over the internal Antenna. WiFi signals are sent over both, internal and external Antenna. A Bluetooth and WiFi combined module is integrated in the VCU: Alps UGKZDA2001AC.
Bluetooth
· Bluetooth operates in the 2.4 GHz band (2402 ~ 2480) · Bluetooth works in both the BDR and EDR · In the VCU the Bluetooth operates in the Classic and Low Energy modes. Bluetooth operates in
the 2.4GHz ISM Band: (2402 2480MHz)
WiFi
In the VCU, the WIFI has the following operating Modes. The device can connect to the external Access points in Station mode. The device can also operate as an Access point.

Used WLAN Modes: · Station Mode (STA)
o Device does not connect to external AP on DFS Channels
· Access Point Mode (AP)
o DFS channels are not used
