I have just bought a NavionTruck, Plus Truck Q71 7" Europe Maps and believe me it was a great acquisition. I work as a truck driver in Germany and it helps me a lot. This truck has installed a TomTom work system but not updated so i use my Plus truck Q71 which is up to date, and now with a new poi's. Great!
I know many people who are using this device, you have made a good choice, I know this company and they are working on a new navigation software that you can download to play store, I've talked with them and I have been informed, I think it will be fantastic
