Hi

 

I have a Superb Sportline MkIII (hatchback) and I'm trying to find a suitable roller blind for the inside of the back window to try and block out the sunlight for when the dog is in the back.  I'd prefer something that sticks on with suction cups or an alternative non-permanent method.  Has anybody found such a thing anywhere that they are using and happy with?

There's a factory option for the sunblinds on the back, I'm not sure if it's easy/possible to retrofit it tho.
