I just got one of these as an upgrade. I had the k1m KRZR which was great except for custom ringtones. So anyway I was wondering if anyone has any info on the Adventure V750? Two quick questions: 1) Does the V750 stream music via Bluetooth? 2) What will I need to do to get music and /or ringtones on this new gem? Gonna try a USB Bluetooth dongle instead of USB data cable, since the KRZR was a nightmare to sync to my PC do to the dreaded driver convolution. Any help or comments appreciated. Thanks in advance for your time and interest.
