Just had my Sirius satellite radio (the Audiovox unit) installed in my nav area and after I left the shop I suddenly see the service engine soon light come on. Do you guys have any ideas on what it might before I take it in to the shop?

 

Installing the unit wouldn't....or at least shouldn't....have anything to do with the service engine light. The only thing they use to install it is the ground and switched wire as well as the antennae plug behind the radio....all things that should not throw off the SES light. I would take it to the dealership and see what code is being thrown.
