I'm starting to think it's not the best thing, has a few glitches that seem un changeable, the connection seems ok 80 % of the time but there is a few fundimental glithches between my Nokia 6230i and the kit, like when the auto keypad locks the radio mutes, sound small but if you're in and out of the car a bit a real pain. After using it for a few days now i'm keen to return it to be honest but not sure how that'll go, i've had genuine nokia in the past, far far better! I think i'll switch or ditch the audio mute and just hit the button on the factory stereo ans see if that makes it a better thing! I'll keep ya'all updated!
