Hello all,

Was looking for a fix for an issue I have. I don't know if it has been asked yet but I've searched around and all the wroung topics come up when looking.

I fitted a 3G+ into my 2010 S5. I have the MMI app on my phone which currently only half works. I can use media player and nav but I would very much like to be able to use the aux heating feature. I have all the parts for the heater retrofit and I am going to tackle the big undertaking but I would like to also use the function on the app. I understand my vin isn't a 3G+ MMI vin therefore I cannot use audi connect through audi. I currently have a SIM card for t-mobile for my maps and connect services.

Can anyone tell me if this is possible to do? My app currently says

MMI connection activated
Wifi connection activated on phone
No connection to vehicle possiable

Thanks in advance,
