I have the firmware 5.70 in my Nuvi 1310. When I have try to check the additional files through the WebUpdater it advice to install the firmware 5.70 again. I see that GarminDevice.xml file (which place in the Garmin directory) has the strange symbols in the end. So the WebUpdater couldn't check my device correct.
When I downgrade to the previous firmware (5.10 or 5.30) I have obtained the same non-correct GarminDevice.xml.
Does anybody else has the same bug?
