Actually the check I wrote was for $47,438.49. I could write that check because I don't waste my money on things I don't need..That's the same reason I have been able to write a check for most every large purchase I've ever made including the nice two story brick house I now live in on 65 acres..
Check out the app called HereWeGo. It is an offline navigation app on android and iCrap. It downloads the maps to your phone then you don't need cell connection--it just uses the GPS chip in your phone to navigate. I have used it across the country and in Canada and it is solid.
I don't understand people who navigate by cell signal. Garmin/Tom or whatever GPS have been doing this for decades without cell signal. It is just a gps chip for gods sake.
