I have a audi a3 2014 and can not get a gps signal on my phone to use google maps tried multiple phones and no luck but they all work in other cars main dealership have had the car 3 times and could not fined a fault and want me to pay £1600 for a mew mmi unit but think it will not sort the problem as it would not block a signal to my phone but will still have to pay full price even if it doesn't fix the fault has any one else had the same problem as I've hit a brick wall tia
