Hi I recently purchased a 2010 Renault grand megane Tomtom edition and when I got it everything worked great, when I went into the Satnav to remove the previous owner's data I reset the Satnav and when it booted back up it no longer displayed the radio settings like it should. I have tried updating the sd card with my laptop but I still have the same issue. Any help would be really appreciated.
