Thanks for the links, I have them stored for future use as I will probably try and sell the unit in the coming weeks. I also have a Start 50 but to be honest I think I prefer using the phone app, I am now used to the map in portrait mode with the phone attached to the air vent with the added benefit of no sucker marks on the windscreen. I was using an old spare Galaxy Note 4 with the TTGO app and Sygic Truck, but have now sold it and getting a Huawei P20 Pro for less than I sold the Note 4. Looking forward to trying the newest TTNDS Mod in the next few days.
