Hey everyone. I am installing a radar detector in my 2000 X5. I purchased a cord that splices( UGH, I hate that word!) into a 12 volt source. Is there a 12 volt wire that is easy to get to? I want to use the 12 volt source so that when the key is on, so is the radar detector. The radar is a Passport X50. I really do not want to use the plug that goes into the cigarette lighter. Thanks in advance.

Dave
