The original iGO application has been modified to work with the hardware sound mixer, And the latest versions we (or anyone else) provide are not, meaning if you install one you get no sound, however a member noticed that on another similar unit if you play mp3's while iGO is running it works. (silent mp3?)
You can buy from Halfords (for a silly amount of money) an updated version.
by any chance would you know about what sd card to use as i transferred all my files from one sd to another (original files) and it wouldnt work but stick it back on original it would work.
and do you know any one who has a copy of igo8 which starts up for navsure not bothered about sound at moment
As it's an official update it's locked to the card, As fat as I'm aware any version works, just rename the folders and files to match the original card
