I cant check the original yet as I haven't got a power connector, but the first model is running the outsourced 8412 navcore, and 855 maps.
What is the best way to update? Should I wipe it clean, let Tomtom Home update to the latest navcore, get the appropriate maps and then patch both, or just keep the navcore the same and get the updated map for it? I'm looking for Iberia and UK & ROI.
I am currently backing up the unit to my PC as I type
