I bought a used truck recently and the stereo wasn’t working and I was spoiled by the backup camera, nav, and handsfree bluetooth calling. The truck already had an amp in it, so I had them put in a head unit that works with Android Auto so that I can use Waze for nav and they installed a mic and backup camera. I stayed with the amp and stock speakers that were in the truck. Sound quality isn’t awesome, and there is either a problem with the amp or stock speakers, as sound from the front right speaker is lower in volume than the back and right front speakers. I’ll replace the amp and/or speakers eventually to fix that and possibly add a subwoofer, but I'm not going to go crazy with it. The main purpose was to get the safety/navigation features and to be able to listen to music, not so much for sound quality/quantity.
