I was wondering if anyone else has had problems with dust entering their app radio. It first occurred after just a month. Unit was sent back and was told it was a faulty seal. It's started again now I'm being told that the app radio contains a cooling fan that is sucking in the dust. This sounds like a load of rubbish, so I would be grateful for any advise.

Mine has not been affected but a friend of mine on the Toyota Tacoma forum has this issue.
