Disable rerouting in maps app?

[yum114]

I have an iphone 5s, I will be making a long drive here shortly. Thing is, my iphone is blocked so it gets no service signal. I want to be able to use wifi at home and get my route for the drive. Is there anyway to disable the rerouting feature?
When I stop at a rest area/food/gas station, I don't want it to try rerouting and end up not being able to(because of no service), and end up loosing my GPS directions.

Seems like a bad idea to hope your directions aren't erased from the phone. Buy a garmin and take printouts from mapquest.

Why is it blocked?

Without WiFi or LTE service, how will Maps work? The Maps only download certain segments of map data, it doesn't have every single street built in.

I don't think this is possible. That said, you can buy a smartphone pay as you go for as cheap as $35 (I just did that with a Lumia 520 and am amazed at what a $35 phone can do... Maps works like a dream).

Do it the old fashion way and get a AAA map.
