OEM Weirdness--Data, Power and the Aftermarket
By Brett Solomon
As vehicles get increasingly complicated, integrating aftermarket mobile electronics equipment into them becomes a tougher task even for the most veteran installation staff. Unlike houses that can accommodate any electronics or appliances (such as home theater or washer/dryers), new vehicles are rolling off of the assembly line with new technologies that are not always directly compatible with aftermarket mobile electronic products. Two topics that should be on the minds of your installation staff are vehicle data bus architecture and 42-volt electrical systems.
Data bus architecture can be a challenge to installation staff because large amounts of information for multiple vehicle systems are carried on a single wire. Hence, interrupting that wire to perform an installation can have profound effects on a vehicle's regular operation. Forty-two-volt architecture is soon to be a reality and Mercedes-Benz is primed to be the first manufacturer for vehicles on sale in the United States to change the rules as we know them.
