I am a new RX400h owner...2006 model, I bought it used with 35K miles on it. It is an early 2006, build date is 06/2005. i've had it about a month now and am really pleased with the purchase...my first Lexus. I do have a couple questions..
1) Since it was an early build, the Nav DVD is Ver 4.2... There are 2 versions I can find..5.1 and 6.1. Reading this forum, I have also found the work around for the "I agree" Nav requirement. As I understand it, if I put the work around in, I should no longer have to respond to the "I agree" prompt each time I drive the car. It does not work for me...at least at the current version of the DVD. I don't have a Bluetooth phone, so I don't know whether the work around solves the car in motion, phone issues. Finally the question...would upgrading the DVD to 5.1 or 6.1 enable the workaround? Obviously, I would get the benefit of the updated POIs etc also.
2) The car came with Goodyear RS-A tires on it, not the OEM Michelins. Probably due to the mileage. I find the tires noisey, especially from the rear cargo area. Since the Goodyears are likely brand new, I am not ready to drop $800-900 for a new set of Michelins, which I am told would be quieter. An alternative resolution could be to dampen the cargo area with B-Quiet or Dynamat. Has anyone here attempted using one of these products? If so, was the addition worth the effort? In addition to the Nav system, the car also has the Mark Levinson sound upgrade, so the DVD player and the amps etc would have to be temporarily removed to install the materials.
Thanks in advance for any responses or recommendations...
Bob
