Navigation plays an important role for Car infotainment system . Let’s consider the situation where a driver is traveling to an unfamiliar destination while streaming music from their cell phone and adjusting key comfort features like temperature, seat position, etc. In trying to replicate this circumstance in order to test an infotainment system, an automotive company will need to simultaneously test GPS communication for the navigational system, Bluetooth connectivity to a phone, the quality of the streaming audio, and possibly CAN communication to an HVAC system. In order to accurately test the operation of the system that is performing these many functions, it is critical to have the right connectivity to all of this I/O while also having tight synchronization amongst all of the data. This will allow for a more detailed analysis to understand what was occurring at exact times in different parts of the system.
