Hello. I did an update through Home 2 for my IQ Routes. I really just wanted the GPS correction. There was a compulsory core download as first update. The update box was ticked and grey so not de-selectable. The text said something like "Navcore update for One IQ XL" and other models. Since the full update at boot-up the screen has a large flashing red circle with a white cross. Since then on Home2 my "Restore button" opaque and if I click it a box comes up saying my device doesn't support it. Well it did a few minutes earlier! I'm very disappointed of course. The compulsory update has disabled my navigator. Hope somebody can help me.......Please??
