A5 Sportback - satnav problems

[coachswin]

I took delivery of a brand new A5 sportback in January. Travelling south on the A1(M) to take the A14, the satnav tells you to go into the left hand land (A14), but tells you to keep on the A1(M) (which is the right hand lane). On the bottom of the screen, the road remains the A1(M) for over a mile (although it is actually the A14). Had a similar incident on the M25/M20 Swanley with conflicting information. Audi have advised me that there is a software update due in June which will hopefully cure the problem. A £150 TomTom works better than this!
Have any other owners experienced the same problem?
A nice car otherwise.

Is it the 3G version? I have an A5 Sportback, and my 3G version doesn't like roundabouts. The DIS and map is fine, and points you in the right directikon, but the voice tells you to exit at completely the wrong turning. Apparently it's a known issue, and Audi have been on at the software manufacturer, but there's no fix as yet.
