Review on Challenger Wrangler Receiver Navigation Bluetooth Car & Vehicle Electronics by Paul Opoku

The micro sd card loading is very slow when I start the car and when I change audio sources the current changes, send a signal through my amplifier, make beats in my speakers. This happened with the first and replacement units I received. The sound quality was terrible. The DSP added too much bass which I don't need because I have an amp and a subwoofer. There is no way to turn off unwanted bass without turning off the amp in software. I could barely hear my high frequencies. Loading time took forever.
