Hi Craggy. Not to hijack your thread, but to understand (and ultimately help) -- how/where did you hook up your HQCT to the factory antenna? My assumption from reading other areas, is that the pillar beside the driver-side backseat contains an antenna booster, where you can 'tap-in' to the factory antenna pre or post 'boost'.
1) Where did you hook yours up?
2) What adaptors/cables/customization did you have to do to hook it up
Once I can actually 'GET' mine hooked up I can certainly test it -- but this has been plagueing me since I got it installed (or partially installed).
When I was testing it on my kitchen table, with no antenna, but exposed (vs in the case) I could pick up several stations, and one with perfect quality. Now that it's in my trunk, in a box, with no antenna... I get zip.
I've got an '02 325Ci e46 HQCTi
