"Navigation Unit" slot

Ok, I'm at my wits end. I'm using the Radar mod and it says to go into the "Navigation Unit" slot and update the radar. Does anyone no where that slot is at?

Thanks.

 

it should be under the interior category, where the beam navigator gps unit would normally be attached (think of it like an in car gps system)
so in parts selector, go into the interior section below the body section, then in there several interior slots should be there, if it isnt directly apparent, it might be under a sub folder

 

Search "navigation" in the search bar, if nothing appears then the car you're using is not supported.

 

You rock buddy. Thanks.

Thanks you rock... that worked..

Now my chase mode stopped working and my lights. Good Lord this game is complicated!

 

Try clearing cache through the support tools option of the launcher. Standard should be enough. If it doesn't work try in safe mode, if it works in safe mode that means you got a mod that breaks the game. Start by deleting old/bootleg mods (if you have any), you should find the culprit sooner or later.

 

ah, the joys of mods...
