This is the main drawback of having the heated front screen: it blocks (or reduces a signal) of all electronic gizmos i.e. mobile phones, dash cams, TomTom type satnavs, toll devices etc.
Thats why wireless charging is required as it includes additional inductive connection on the external aerial.
Personally I think its a waste of money in the UKs mild climate. How many days a year below 0 Celsius we've got here? Not many as average winter temp is 4.4C.
In Sweden, Norway, Finland, Germany, Poland etc you can really benefit from this feature but not here...
