The dash cam is a cloud based Blackvue which also saves video to the SD card. But if I wish I can use a smart phone app to download video to the phone or the cloud. That's probably what contributes to the data usage.
I have a secretary in the LH seat, she searches on the phone if we don't have the address. My GPS has far more info than factory units and the offline Here maps on Windows Phones are great world wide. Never been caught out with them and you get 3D buildings etc. About the only thing I have to do is keep some spare 64 GB SD cards in the glove box. Two phones on separate networks and I have yet to need to go online, but then again, my needs are simple.
