Just bought my first Subaru, a Crosstrek.  Obviously a great reputation and my friends that have/had Subaru's love them  While I am not a car guy I am a utility guy and this checks a lot of boxes.  So far I am really digging it, except for one thing. 
  
At the risk of public ridicule I am looking for an answer.  The radio always starts at the bottom station, not the last station I had on when I turned off the car.  I could be listening to channel 100 on Sirius; turn off the car, Sirius is on 1.  Same thing with AM and FM.  I have never had a radio behave like that. 
  
It has to be a setting, I cannot find it and even checked the manual.  It is probably something obvious so I'll take some abuse if someone can tell me what I am doing wrong.   
  
Thanks
