iPad with cellular but with no SIM installed works well, except not able to get weather radar or metars.
But the map and continuous position on map works well.
I used to have this same set up, but then bought an iPad mini without cellular, and regret it - I have a separate Bluetooth GPS to link with the iPad, and it is ok but a nuisance to remember to charge up the GPS unit, and if i want to use the iPad for car navigation, I find it a hassle to get the Bluetooth GPS out, and set it up, etc. much less spontaneous to use. I guess I am just lazy.
