The device actually connected easily and works quite well. My problem is I have to be very close to the car for it to connect to the Bluetooth. Not sure if this is this particular apps Ben issue or if it is just how Bluetooth is.

The majority of the time when I open this app it connects to Bluetooth, and then starts synchronizing data and the synchronization never ends. While the is doing that it is not usable, it’s like it’s froze up. This has been going on for a few years now rendering the app useless.
