Narrative:
Tracking inbound on sli 319 degree radial (heading 139 degrees magnetic) noticed track to right of (west of) radial approximately 4-6 degrees and increasing -- found front seat passenger had bumped the HSI slave to off and realized 20 degrees of compass difference. Immediately changed course to fly east to remain clear of class B (lax) but possible incursion. Next time use DME to verify lateral clrncs. I had the DME on sli -- should have been monitoring the lax VOR DME. It should be noted that the vtu 075 degree radial (that defines some of the lax class B airspace) is charted but unusable (reference the AFD).

Title: SMA PLT ENTERS CLASS B AIRSPACE INADVERTENTLY DUE TO NAV EQUIP BEING TURNED OFF.
Narrative: TRACKING INBOUND ON SLI 319 DEG RADIAL (HDG 139 DEGS MAGNETIC) NOTICED TRACK TO R OF (W OF) RADIAL APPROX 4-6 DEGS AND INCREASING -- FOUND FRONT SEAT PAX HAD BUMPED THE HSI SLAVE TO OFF AND REALIZED 20 DEGS OF COMPASS DIFFERENCE. IMMEDIATELY CHANGED COURSE TO FLY E TO REMAIN CLR OF CLASS B (LAX) BUT POSSIBLE INCURSION. NEXT TIME USE DME TO VERIFY LATERAL CLRNCS. I HAD THE DME ON SLI -- SHOULD HAVE BEEN MONITORING THE LAX VOR DME. IT SHOULD BE NOTED THAT THE VTU 075 DEG RADIAL (THAT DEFINES SOME OF THE LAX CLASS B AIRSPACE) IS CHARTED BUT UNUSABLE (REF THE AFD).
