Hi,
I have upgraded my TT One XL (32 MB Device) to SE 9.051.503855 navcore. Everything works well except the voice instructions. Voice instructions do work till the TT comes across motorway exists showing lane images. As soon as TT starts showing lane images it loses all voice instructions and sound. The map I'm using is 870.3460. I've tried using navcore SE 9.026.483454 as well. It's the same.
I've formatted the SD Card before installing ...
