Volvo CarPlay Update with Hardware
Description:
Some Volvo trucks were built with an infotainment unit that does not support Apple CarPlay. To enable
CarPlay, the infotainment hardware must be replaced and additional software must be installed directly
to the infotainment unit. The software update process does not use TechTool. This update also includes
updated navigation maps.
Corrective Action:
Replace the infotainment display and SEM (Service and Entertainment Module). Refer to Special Tools
Bulletin STB20-002V v2 and use the USB stick to update the software according to the campaign
instructions. The USB stick is preloaded with the appropriate software.
