Just got a new Razr V3xx and have some questions. It pairs fine w/ my 2006 X5 stock bluetooth, downloads the phone book, looks like all is fine. Can even place and receive calls. Problem is it doesn't stay linked up. Continuously drops and then re-establishes Bluetooth link.I know the Razr V3 is totally compatible, wondering if the V3xx has some issues. Firmware, software problems??? Any help is appreciated.
