Hi, I´m from argentina. sorry for my english. The HU is great about BT. Despite the quality of the sound is far away of being excelent, (I used to have a nakamichi HU), the BT works perfect for controlling winamp, windows media so you can control the volume, skip a track, browse folders and control almost everything from the stereo.
The connection with the phone is perfect. It had never failed with almost 10 diferent phones that I used. Nowadays I have a motorola a1200 and i ´ve tried with the v3, v3i, v3x, nokia n80, qtek 9100 and everyone worked perfectly. It´s a very good option for a fair sound quality and excellent BT device. Once again sorry for my english.
