Major problem: F8Z445ea is too short for some cars eg Citroen C4, so is useless for me and others.
Belkin F8Z571 works, and has iPhone cable, buy it instead/as well and just get an extra micro-usb cable.
Minor problem: F8Z445ea gives a low humming noise, F8Z571 is silent.
And just for info: F8Z445ea blue light, F8Z571 green.
