deleting routes in satnav
 

Can anyone help please.
I have just bought a 2006 Cherokee limited crd.
Have upgraded the satnav with a 2011 cd.
I am trying to delete the stored routes, following the manual , they get deleted.
Then when I turn off the ignition and turn it back on again they reappear in the memory.
What am I doing wrong??

Most of us don't have that, in the us you have a liberty. I imagine jeep forum maybe a little more helpful to you
