I have a friend who installed a Touch & Go from an Avensis 2012 to his Avensis 2009.
The problem is that the navigation is always getting behind with around 1km.
So it shows wrong on the map 1km or something like this.
Any idea what can be wrong ?
Also, he does not have an USB cable to make an update to the software, and Toyota here can't help him... any idea where can he get such a cable ?
