iPhone 5 iOS 6.0.2 will not stay connected

Im another review that states loss of connection. Worked 1 time and now it connects over BT than disconnects after 3-5 seconds. Ive spent hours resetting network settings, reset all settings, restored my phone… No change. I hope tunelink figures this out or mine will be returned very soon. Ps sent email, still awaiting reply. Poor product support.

Update, sent tunelink back to manufacture and it was promptly replaced. Have been using for almost a week and it has been flawless. No drops in BT connection. Not sure if I received an updated tunelink or if I just had a defective one to start off. For sure recommend but test it early and if it is not staying connected I then I recommend contacting tunelink for repair or replacement. The customer support was great once the ball got rolling. Thanks tunelink.
