Decent Value, a few bugs need to be worked out

October 20, 2016

If your car is wired for bluetooth I recommend that route. If your car is not wired for bluetooth, this is a good alternative. The crux unit can be buggy at times. The instructions mention that when there is a call in progress and you push the iPhone button to disable bluetooth to talk on your phone you need to pair the phone again. It seems after this even after I pair the phone after it was disconnected, it never stays connected. I must manually connect it in the bluetooth menu every time. You must delete the phone and start over and pair it as if it was installed. This can get annoying at times. The other issue I have with the unit is that you can answer with the a call with the phone button on the steering wheel, you can not end it with it. It will stop the audio and switch to the radio, but the call is still connected on the phone and not hung up. The purpose of the integrated unit is to make driving safer, but the unit requires me to use the phone controls almost exclusively, which is counterintuitive. The other strange problem is that even if I have full bars and the person I am talking to has 3 or 4 bars, the audio at times is not clear and is impossible to understand the caller at times. Calling back did not help fix the problem. Works ok most of the time. It seems like most of the issues are with the coding of the unit's software.
