Hi guys,
Hope someone can help my friend as he's tried and failed to solve a problem with his evoque.
Lost the navigation screen and everything associated with it. I think it may of been since the battery died, but unsure.

Have JLR SDD and on the ecu tree we've got green ticks on the CAN-H apart from VIM.
On CAN-M sometimes it shows a big red X across the entire row, however, when the car is started the ecu's get the green tick.
SUB_MOST always remains big red cross's across all 3 ecu's (aam, acm, dabm).

Thoughts?
