These are old pics from E34 (V1 next to mirror) and E39 (V1 is in the far right top corner). between the two I prefer the top right corner, it is probably still at an optimal position and outside of the driver's reach, which does not alert a "vigilant" cop as much - cops usually look for a detector within the right hand reach... while it is only illegal in VA and DC, cops in many places do not like dealing with the detectors thus they single out the detector users as more prone to speeding...
