Not working properly screen upside down and backwards can't read anything  anic435i  1 star

I just bought this app I can't read anything it's all backwards upside down can I get some help please?


Incredible Support  FallbrookMac  5 star

First of all, having Bluetooth connectivity for the JB4 has been a valuable enhancement. When I had a problem with the BT hardware, I sent the unit to Donnie and after a few email exchanges, he fixed the problem and sent me a replacement unit. The app quality is outstanding and support all the more so. It is amazing that there is such an outstanding product for a niche application. Just get it! If you already made the plunge to get a JB4, the Bluetooth interface will greatly enhance your investment.


Username/password server fails  snarf`  2 star

The app was GREAT until the username/password was implemented. Now I can't use my iPhone turned iPod for sole purpose of using it to connect to JB4 unit. Remove the username/password and this app will gain back its 5 star rating.


Country Check for Passive Delete?  photosbyCALVIN  1 star

No thanks.


Awesome  E90dread  5 star

It's money well spent!


Great tool  Sanchezable  5 star

Love using the app. Updates I hope to see. A gauge for fuel economy (miles per gallon). Add more of the steering wheel controls in the app for easier control. Also a eco map to maximize fuel economy, similar to eco and sport on modern BMWs.


App needs updating  msafar95  2 star

This app needs an overhaul from top to bottom. The UI is very unfriendly. For the price of the app, it'd be nice fnthe developers atleast made the app look good

Fraud  Shh73  1 star

This app is a joke. Charged me over $30. Already called my credit card company and for a non payment and fraud by the app creator. Don't buy it!!!!


Major flaw  leCarbone  1 star

Needs security. There is nothing to stop someone else from connecting to your car and changing crucial settings causing damage.
