There's been a severe lack of decent mounts for your cradle for this car as the Brodit one
Is WAAY down in the passenger footwell
And The Dashmount one
Flaps about like a flag when its got a cradle fitted on it
Look at these though
Not cheap.. Prices start from $35.00 USD plus carriage from across the pond but a nice bit of kit all the same, will fit stuff on the drivers side too if required.
Ideal for folks running satnav on their phones
Would work on an Audi A3 too as the air vents are the same
