My car just got back from the shop and the bose headunit doesn't work. I checked the fuses bose and audio and they are both good any Idea what this could be or is my headunit just all of a sudden toast?? It worked before i sent it there and now nothing. My abs light is on to ,but thats a whole other story....

 

Tell the shop to fix it ?.....

Test all fuses with a meter, probe, test light, or something of the sort.

What exactly did said shop work on?

 

The fuel injectors??
