Hi all ive managed to do the hack no problem with backups of both flashdisks and managed to get igo8 working perfectly. Only problem is that the stock nav now only finds around 5% of postcodes in its database. Ive tried putting back a copy of my flashdisk2 (map storage) to no avail. Can any one help? 

**UPDATE** borrowed my friends 310bt which is stock. Borrowed his flashdisk2 and still nothing. Ive copied my original flashdisk1 back over and my nav actually went back to 1.004 and postcode search works great. put my hacked version back and limited search and igo 8 and apps still work
