06 Gs430 Nav Upgrade

[The_Ox]

I searched but could not find out how to upgrade my Gs from 5.1 to 7.1 so thats my question. I put the 7.1 in and the nav says searching disc or something like that. Where can I get the info to do this upgrade?

Thanks

Your map disc must be 86271-3304X... the higher the last digit the better. If the new disc you bought is anything but -3304X then it will not work.
