Make sure there is a logic_playerproxy entity and at least one jalopy with EnableRadar on. Then fire an input of:
logic_playerproxy SetLocatorTargetEntity entityname
Where entityname is what you want to show on the radar.

Edit: Unless you mean the one on the dash board of the jalopy, in which case it doesn't work.

I found out that you can fix the radar, but it has to be done client-side. You must copy vgui_screens.txt from Half-Life 2\ep2\scripts\ to Synergy\synergy\scripts\

I made a script that should be able to detect where those directories are and copy over the file:
https://www.dropbox.com/s/gvs19umeh4egzlk/JalopyRadarFix.txt?dl=1
Rename that script to end in .bat instead of .txt and run it to automatically copy the file it needs.

This text document can't be anywhere other than Synergy\synergy\scripts\, I tested as a workshop addon, item-replacement, in custom, in downloads, etc. It only works if it is placed directly in Synergy\synergy\scripts\
