2011 xc90 nav screen issue
 

I could be wrong, but I don't believe the navigation system screen in the 2011 is touch sensitive. There's no option to disable the navigation system, however you may be able to accomplish this by removing the associated fuse.

Sensus-Navigation manual...
2011 Volvo C30, S40, V50, C70 & XC90 RTI Sat Nav Owners Manual US

I have a 2011 XC90. In Australia at least, there are two types of Satnav that came with an XC90, neither are touch screen.

My one has controls on the back right hand side of the steering wheel, where your fingertips would be if you hold the wheel in a 9-3 position. This type should also come with a remote, though mine didn't when I bought the car 2nd hand

The other type just has a remote, no steering wheel controls, but I think that would be on pre 2007 models so on a 2011 you should have control behind the steering wheel.

How are you operating it now?

Hi I bought a Volvo XC90 2011 and the Satnav screen is not coming up from the centre of Dash and also the stereo comes on the goes back of after couple of seconds ,Are these 2 linked to each other if one don't work then the other stops working ....has anyone has had the same problem ,I have even taken another stereo out of another XC90 and its doing the same thing comes on and then goes of after couple of seconds .....I have checked all the fuses and they seem to be fine ......Anyone got any ideas ?????
