Impeccable, meets the need

A device that works perfectly with iPhone 5S. Quality Made for iPhone (recognized immediately).
Allows both charging and FM transmission.
Used with 3 applications open at once: Deezer, Wikango, GPS guidance => music plays, all alone down Wikango alert when me and when the GPS has a guide to announce.
The transmission quality is good in all conditions. If the wire droops well, the reception is excellent even.
Very simple operation (no need manual ...).
The hard part is finding the free frequency ... But it is the principle of these devices, to transform his old car stereo in great jukebox ...
The app Belkin worked the first time. No problem for me.
I definitely recommend.
