Not sure if I'm on the right thread but here goes anyway. I'm having problems with my unit receiving a GPS signal. At first I thought it was just the antenna so I bought a new one. I ran the autodetect option in the IGO program but after scanning for the antenna, it says that no antenna is connected. I have checked the connector on the back of the unit and it has got 3v so is giving power to the antenna. Could it be the GPS card is fried?
