HTC Mogul / XV6800 / PPC6800 / P4000

in my experience it's more the car that matters than the kit...I've used a few, sony, nokia, motorola etc and found that my freakin tomtom910 works better than those kits. Strange...Anywho, if you're in a car that's quiet like a lexus, or other high end car just about any current kit should work fine. In my 2003 altima se the tomtom910 is not useable, just too much road noise though it does work fine at a stop or very low speeds with windows and moonroof closed, but in my 2003 jaguar the same tomtom910 unit works fine at highway speeds with the moonroof open, but because of switching cars frequently I just stick to my BT earpiece.
