my brother in law has a 14 ram megacab...... a company out here in socal used his truck to design/program the screens for the ram trucks. They gave him a free screen for his time.
Took only 2 weeks before he went back to the place and had them reinstall the factory equipment. The blutooth was horrible, not all the buttons worked properly, when he used the voice command to make a call it would automatically redial the last person he called, the stereo didn't sound as good, took forever to boot up. He got fed up after his battery's died twice. The company even paid for 2 new replacement battery's thinking they were bad, but they continued to die.
The screen looked cool.....but that's about it. Couldn't tolerate all the little problems even though he didn't have to pay for it.
Hope you have better luck with yours.
