An excellent price / quality ratio. Indeed, the quality of your HP will then play the final render but the product point of view the sound is optimal. I feared two things when buying: 1) Installation ==> no worries most complex in my case was to dismantle the old original position (Renault Megane). Note one thing: no connection to the steering wheel. In terms of connectivity I just needed a male / female antenna adapter (but I had anticipated the order, thank you to the other reviews ^^) 2) The USB max ==> I use a 16GB drive, no problem
