I am just wondering where do you mount your e-tag (the device to pay toll automatically in motorway) in your Porsche? We call it the e-tag in Sydney Australia. But I think people in other country may also have the same problem.
It is recommended to be mounted in the middle and 7cm below the top edge of the windscreen. But the rear mirror is there. If I mount it below the rear mirror, it will block my view when driving. The device we are using here is about 10cm x 5cm and 2.5cm thick.
Any suggestion will be appreciated. Thanks.
Chris
