Hi I wonder if anyone can assist please? I'm potentially buying a 2013 Edge and bringing it over to Europe. Over here, we use all 10 decimals of the FM frequencies versus just the odd numbers. I noted on a rental Edge I had there was a soft button for reconfiguring it to European settings but couldn't press it as greyed out. Is there any way to do this? I saw there was a German gentleman who had successfully imported one. Many TIA.
