Hello,
I have updated yesterday my Mio Spirit 7500LM with the latest map for all Europe , using Mio Desktop software. After update the route calculation is very very slow and if I insert a major city or any adress ( from any country ) which is located at more than 600-700km the device will calculate 10-20 minutes and after that when you select any route type ( fast, economic....) it shows a message : "" Route cannot be calculated "" and you have only the possibility to press the OK button for exit the calculation. Before this update , with the old maps the device has worked perfect. I have purchased it in Nov 2015 and I had no problems in the past with the device. It is a very good gps . Also I have updated yesterday the WNRO to have correct date/time in the device and I'm not using any microSD card. The maps of Europe all saved in the internal memory of the device. What can I do ? Please help me.
