Back up camera guide lines???

When I first test drove my 2014 Tacoma it had the guide lines that moved with the steering. I bought this and somewhere between the first test drive and now the lines disappeared (I have the Entune plus without navigation). I took the truck back to the dealer and they said Toyota told them that my model does not have this feature.
Obviously my radio is capable, but i'm assuming that there was an update that took this feature back off.
Does anyone know of a hack to put the lines back on???
Thank you for your help.

 

Dude, your going to get folks fired up if you keep posting the same thing.

I have a 14. Has guidelines but they have never "moved." Perhaps you test drive several vehicles and mis-remember this as a feature on the one you bought?
