Hello all,

New to the forum and have been researching radar systems for the 2003 BMW E39 (540i) I recently picked up. I'm pretty much at a loss on where to begin at this point. I have heard of Passport and Escort and Valentine, but my understanding is that all of these units are in-car mounted units. I would really like to preserve the look of the car as much as possible, and I'd much rather have that stealth radar presence - so I'm looking for the best options for through-car (bumper-mounted front & back, hardwired) radar/lazer detector/jamming systems that would be most compatible with my 2003 E39

Any advice or direction on where to start my research or what brands/models would best accomplish this would be appreciated! Thanks very much!
