Dear Audi fans, Today, my brother had ordered a laser detector from Home shopping network for only $98(including tax and shipping). Its feature, something like Vg-2, Ka K and others. Is it a good price? What is all those Vg-2, K, Ka about ? I really know nothing about radar detector. Can anyone be kind to give me some explanions about this? Thank you Albert Ng '87 5kcst
