Recognition of the Iphone 4 is automatic.
Product supplied with a remote control.
As for the sound, for a product of this size and at this price, I do not think we can do better.
I even think (but without having compared) as mini-channels 300 are no better (except for play CDs ...).
No saturation, a welcome presence in the grave.
Tuning into FM is very good.
The display reduces its intensity automatically in low light.
In short: a product advisor
