Bought the app-cessory at best buy mobile at square one. It never worked properly. I followed the instructions to a tee. It paired with the iPhone the first time. Then I downloaded the app and it just didnt work. Sure the display said it was broadcasting on 88.1 but it was nothing but static when I ran the iPod app and switch the output to Bluetooth. Then, all hell broke loose. Bluetooth disconnected on its own and refused to reconnect after a number of times I turned off/on my car. I had to delete the bt device and re-pair from scratch. The app kept saying the device was off-line despite it being paired and connected. Did a full iPhone reset, deleted the bt device, shut the car down. Tried again, failed. Did this for 2 hours to no avail. This thing just refused to work.
