Have you tried waze? Totally free and get traffic updates if connected to WIFIok, good news i think i managed to get mirrorlink working. had to clear the cache (which is a bit odd since i've never used it before) and downloaded the floatingapps app. Then Sygic and violla i have a sat nav. Going to test fully in the morning but it looks promising. Its £12 for a license and I'm happy to pay that for a working system.
