i have galacticMap3D MFD add-on. thats what you mean to?
No, that add-on shows you where things are, and is useful (I use it to eyeball launch windows) but it isn't a navigation tool.
Your two best options are, as mentioned above, TransX and IMFD. TransX is like a VERY advanced TransferMFD, and you will need to know how trajectories work to really use this tool. It is the only one of the two which can be used to
plan a slingshot or multi-sling trajectory such as the Voyager or Cassini flights. IMFD can be used to perform those flights, but you will need to have some information first (launch and swing-by dates, etc You can use TransX to find that, or use historical data, etc.
For TransX tutorials, check out the ones by FlyTandem, the community guru for all things TransX (use the forum search function to find those).
For IMFD, I shamelessly plug "IMFD Full Manual and Playbacks" by MarkL316 (with some help from myself). It can be found on Orbithanger. This comprehensive guide is the most thorough treatment of IMFD available, and shows the correct set-up to most possible flights in Sol system. Also, it includes a simple, repeatable process that can be used to find a launch window, and complete just about any single flight without any "external" data - and it doesn't even require you to know what you are doing.
