Hello,

Lets check for power at fuses # 36 and #40 in the trunk fuse panel. Here is a guide to help and the NAV system wring diagrams so you can see how it works:

Good job on the fuse can you tell me if the fuse has power? Here is a guide if so please check the ground in the same manner (switched to power) and if okay the unit is no good and needs to be replaced.
