I purchased an Android G13 and installed it in my 2017 Tundra, non-JBL truck. It's a definate upgrade as regards capabilities. The sound quality is lacking, however. It seems to rely heavily on the smaller front speakers making the sound 'Tinny.' and hardly no BASS. I have adjusted the Amplifier/Equalizer in numerous configurations. I am able to get a little more volume from the rear speakers, but the sound from them is muffled and 'Muddy.' The sound quality is markedly inferior to that produced by the original Toyota Head-Unit. When i purchased the headunit I was using the stock Toyota speakers was having the same problem with the stock speakers so then i upgraded the front 6x9's and the rear 5.6 hoping that was the problem. but still the same proble.
