There are alot of navigational systems around, give some details on yours. Windows 10 was/ is supposed to run on ARM processors but because they didnt want to release source code the processors are restricted. Windows CE RUNS on most ARM based chips.
I would go the latest CE route depending which ARM core you using, so far i dont mean to be offensive but you havnt given any clue to which ARM chip! You are aware just how many ARM core based chips are around? Not to mention the number of different types of ARM cores.
Then you also have the windows 10 IOT OS, this is very different from the normal windows 10 however, I am pretty sure it can run on the raspberry pi which is where I would head by the sounds of your project.
I dont like win10 IOT OS, I would go linux route with ARM core and there is plenty of navigation software for ARM based cores.
Can you give more details? as it stands you could use a special win 10 version but would be limited to snapdragon chips with ARM core, win ce will run on most decent ARM cores but obviously dont try it on a M0 core! Windows 10 IOT was designed for IOT devices running different ARM cores but its a mess IMHO. Keep in mind alot of modern medical equipment are running windows on ARM based systems.
