If you go to Valentine One radar and laser detectors and read the FAQ's you will see which cars and windshields reduce radar detector detection the worst. Just about every car reduces radar detection range. Not all are as bad as others. Each manufactor has different films. Mike valentines website gives you all the answers to these questions? I believe speedzones did a test on remote system radar detectors versus dash mounted. In some cases the dash mounted outperformed the remote. There is not that much difference in range either way you go.
