JB4 Connect Kit - Rev 3.7

The Original Wireless Hardware for JB4 Mobile!

The Connect Kit/JB4 Mobile system was one of the first successful wireless tuning interfaces on the market. With over a decade of development, we've continually pushed the envelope regarding what a mobile tuning interface can do. Made and supported here in the USA.
