My mechanic (He knows what he is doing) & I tried 5 times to get it calibrated in an open field so there would be no interference from other vehicles, buildings, or metal. In my 2005 Dodge Dakota, if we got the N/S right, the E/W would not be right. When we got the E/W calibrated right, the N/S would be off a good bit. We did this five tries...no go. Returned for refund. Good Luck
Pros: looks good
Cons: could not get to function correctly.
