Newbie - Flashing mileage

[NikkiNew]

Evening, I am a newbie. Recently bought a 2015 Fiat 500 Abarth.
Does anyone know a good independent Fiat Specialist in the Farnborough, Hampshire area.
As I have got the flashing mileage (fitted after market stereo) but was flashing before with the standard stereo. My mechanic tried to do a proxy alignment with his snap on scanner but says unit inactive. Any idea what unit it is as he is unable to get into the proxy. Also anyone know of a good aerial as got a head unit with DAB and my aerial is not picking up a strong signal.
Does anyone have an O/S DRL for sale? Please
Thanks
Nikki

I used a Snap On Zeus Diagnostic tool from a friends garage when repairing my daughters 2012 Punto Evo due to a poor previous repair on a passenger seat occupancy sensor damaging the BCM (body computer) I fitted a new BCM and was able to use the Snap On tool delete old error codes then locate all the units fitted to the car and do the "Proxi Alignment" so the BCM could talk to the rest of the car, I then deleted any further error codes and car has been clear ever since with no flashing speedo, stop/start and other faults that that throws up.
Apart from that on previous Fiats I have had issues with non original stereos, incidentally other Forum members have had issues with non stop/start type batteries fitted and bad earthing etc.
Finally many here use the MES diagnostic program designed for Fiats with much success and will be able to advise you better than me.
