Can anyone help please. My unit worked perfectly until I suffered sudden illness. I was off work 17 months. On my return to work I plugged into my pc and did my updates and renewed my live services. Everything works except live traffic. It works when connected to the pc but when I disconnect I get gprs disconnected. For 3 weeks I have been emailing back and forth,factory resets every 2 days. Have even been stood down the garden for 45 minutes holding the unit facing the sky.Today they want to know how long the battery lasts. My patience is now wearing very thin. Every phone number is disconnected and I cannot find an address to just ask head office for advice.
