With a couple of very recent threads about RNS-Es being stolen (here & here) I fear we may be at the start of a spate of thefts. The theft of your S3 wing mirrors is an expensive problem but smashing your window to nick your headunit is a lot worse. With the wingmirrors problem quite a few rightly stated that we shouldn't buy them from eBay as we're just feeding the hands that stole them from another A3 owner, and it's a vicious circle. The same will apply with RNS-Es, so one thing we ALL need to do is buy a UV marker and stick your postcode/VRN/chassis number all over the unit. I will be buying one ASAP myself. We may be able to take it a step further, perhaps hold a database of serial numbers next to their owners so that we can contact people directly if we happen to come across one. One thing we really need to do this time is gather EVIDENCE. When we find a unit in the wrong hands we need to be able to positively show that unit was stolen and hopefully have action taken against them. Thoughts/ideas/suggestions?
