    I have the MMI system in my S4 and the radio is basically lost tuning thru all stations
    the signal meter at the bottom gives me 5 bars and yet the radio stations still dont tune in worth a ****

    any one got any ideas ?

    Signal bars, those at the bottom are for the Bluetooth phone connection, not radio reception.

    Is it a cab by any chance?

    BTW the B7 doesn't have MMI.

    Yes I know the RNS-E says MMI at startup but that's an idiotic decision by a mad marketing buffoon at Audi that has caused people to spend £200+ on the wrong map DVDs because they think they've got MMI.

    The RNS-E and MMI have absolutely nothing in common - different hardware, different software, different maps, ...

    Got an update for this. I bought keys to pull the radio out and I've found the Ariel connection on the head unit to be loose I took the back plate off and it looks like the soldered spades have broke away from the circuit board. So if I hold the Ariel cable up the radio works fine

    Well either needs repairing or replacing, we can look at either option, but I can assure it wouldn't be a cheap fix if its broken the pcb track, possibly new board.

    You can post yes, but depending on the level of damage, it sometimes is better to change for replacement unit.

    Costs vary tbh, as they are mk1 & mk2 units.

    Send pics & we can have a look, but only a personal inspection would allow a proper analysis for costs.

    Well that's definitely been knocked as the plastic housing is broken aswell.

    It needs properly inspecting tbh, so up to you how you want to go forward.
