I agree with above. I own the 6990 and the response time is sssssssllllllllooooooooowwwwwwww. Get the point I recently got the 9990HD. Hands down faster and better UI than the 6990. Yes you can get the 6990 for a cheaper price, but you will have to live with the sluggish speed. the 9990HD also looses the voice commands, but I never used them anyway. Wicked has a deal for the 9990HD and I think that Kenwood just came out with a $100 rebate too. I do not consider myself to be a fanboy of Kenwood, rather I did a lot of homework and made a well informed choice for my head unit. I used to be all about Alpine until other brands started stepping up their game.
