Practical: it simply plugs into the cigarette lighter and reads the tracks on USB key, putting the car radio to the frequency displayed ... hop, we go to listen to his favorite songs!
The object seems to be delicate attention, I 'have not used the remote control (which seems a good addition).
We just put in random mode (long press play button) to change the sound (long press forward / back).
However, I do not know how to keep in memory frequency - when the lights he recovers on 87.5 so it must be set again to the right frequency ... if anyone knows the manipulation I'm interested.
I read comments on the sound quality ... I admit that in a car hi-fi seems pointless! For me its very correct USB, its pretty poor JACK terminal (too low), not tried its memory card.
For the price! ... Only annoyance I bought 9.90 there 15 days, it is sold today 2.90 ... but I'll maybe buy a second (for the second car).
