Knight Rider Kitt voice isn't free! It'll cost you $15 US with tax & foreign credit card charge. The images are free. The sample sounds kinda lame to me, but it's too short to tell for sure. I have John Cleese & it's annoying 'cause he says "In 3 hundred yards, you have reached your destination. You can get out of the car now, but I am not going to help you with your bags. From now on, you are on your own." It would be OK if it waited till you actually arrive before telling you to get out of the car.The only other thing I have heard that is not just turn instructions, is the u-turn instructions. Basically, you have john Cleese's voice giving directions, but nothing funny or interesting. Unless someone tells me that some others are a lot of fun, I will not pay for a celebrity voice.
Cheers,
