Well I havent received my MK3 as yet but have sucessfully installed my aerial and cabling all ready to go thanks to this site......just one more question? once i plugin the MK3 will the option(navigation) automatically appear on my computer screen? or do I require to code it first?is there any set procedures I need to do.....I did do a search and found lots of install stuff which has helped me but nothing on powering it up.

Thanks
