I've had my x50 for a little over a year now. While it's been great, I'm still concerned with the ka detection. The troopers here are deadly with the instant on ka, and I've been nailed a couple of times. Thought I was driving smart, always cars ahead of me, but the first indication I get is a ka alert and he's there with the brake lights on turning around. Either he's only gunning me, or it's not picking up the cars ahead that he's hitting, while can see their tailights. Just wondering if ka detection is improved enough to swap for a new rx 65 and a little cash.
