Samsung SPH-A900 Bluetooth problem

I have a Samsung SPH-A900 cell phone and a Motorola IHF1000 Bluetooth carkit. I get frequent phantom phone calls while driving. The carkit rings as if there is an incoming call but there is no call. My cell phone does'nt ring while this is happening and there is no indication of a missed call. Nether Motorola nor Samsung have responded to request calls. Has anyone had this problem?

Several Motorola Bluetooth products do NOT work on CDMA networks. This is true for the Motorola H500 Headset (stated on the packaging). I've had problems pairing several other Motorola Headsets with the A900 as well. RAZR V3 & Blade A900 not playing nice???

Maybe...
I just downloaded a new (2nd one in 5 days) firmware update for the Samsung A900 phone. That may resolve the problem...maybe not. The installation tech said that both the A900 and IHF1000 equipment was brand new technology so I'm hoping any incompatibilities are resolved. Too bad the manufacturers don'e respond to tech issues.

the H500 worked fine for me on verizon, but the box does say is won't work.

I'm not sure what an H500 is but the IHF1000 Motorola car kit gave me about 10 more phantom phone calls this morning. My cell phone (Samsung SPH-A900 (Sprint)) didn't ring at all but the carkit was going nuts. Too bad Motorola won't answer my tech support questions. We operate a fleet of vehicles and I think we're going to dump their system.

Well....Samsung finally admitted that there is a Bluetooth compatibility issue with their A900 phone. They promised that they are working on a software upgrade. It took two weeks for them to admit the phone doesn't work so I would hold my breath for a fix.

The H500 setup works perfectly for me.

What is the H500?

Does anyone know if this issue has been corrected?
