Replying to: vdoc (Oct 03, 2008 7:27 am) Unfortunately, from my experiences, it seems it is the Samsung phone that causes these problems. I've had 2 Samsungs, the T-809 and the U-600, and both do not reliably pair with my RX400h. We have a Bluetooth Valet who works for our Lexus dealer, and he verifies this - he says Samsung Bluetooth technology is not as good as Motorola, or Sony Ericcson. I finally got a SE W580i which works perfectly with the vehicle. I also got an Apple iPhone 3G at work, and it also pairs consistently with the RX400h. However, many Bluetooth features like sending your phone contacts to the car, do not seem to be supported by the iPhone. But at least the iPhone pairs up every time, which is more than I can say for my Samsungs. Replies to this message: vdoc (Nov 19, 2008 8:45 pm)

Replying to: kyxydj (Oct 15, 2008 8:53 am) well gang, here's a follow-up and it ain't pretty. After contacting the Lexus customer relations office in CA about the problem, I met with the regional electronics specialists at my dealer's. They were able to reproduce the problem in my car and with another car of the same vintage. The week before that I had had my car in for service and was driving a new RX as a loaner and never had a problem. Turns out that the Bluetooth/Navi in my 2006 400h is generation 4 and the newer cars have generation 5. Lexus admits that the compatibility issue appears to be a problem with generation 4 navi and my Samsung phone but had no comment when I pointed out to them that the Lexus Bluetooth website listed my Samsung phone as being compatible with my year and model (and still does, by the way..). Although the obvious remedy would be for Lexus to upgrade my car to gen 5 they have refused citing that "it can't be done". Instead, they have offered me money to purchase a new phone however it would be up to me to establish compatibility which suggests that Lexus doesn't trust the Bluetooth information on their own website. A sad state of affairs.
