This is my install of Radar in a 2011 VW CC Sport (no sunroof).
This WILL switch with Ignition on.
It turns out you DO NOT have to remove the light Bezel as some pictures on internet indicated.
That was MUCH harder to get off than the Speaker Bezel (which is all you need to snap off to get the power you need).
Under Speaker Bezel you'll find two Torx Screws. Remove those two and everything comes down nicely (couple very light snaps still holds it in place). There are HOOKS on the light end (towards front of car) so pull down from the Speak grill end.
I highly recommend using a hard wire with a fuse ($10.00 from amazon NO REMOTE), as the fuse on that ciruit is probably to heavy for the radar detector. Remember the fuse is to protect the Radar internals in the event something goes wrong inside the detector; it does minimal damage. You only fuse it based on the current that device uses. If it suddenly uses a little more current you want it to blow quick as possible. Those unfused invisicords are a BAD DESIGN IMHO.
It is very rare I need the mute switch with a 9500ix so I don't bother with a remote.
Unsnap Speak grill Grill (I bought some nice SIR Tools plastic pry tools, works nice, not a scratch)
Shows Speaker grill removed, the tab shown is towards FRONT of car
Nice Ground (I cut the loop provided on hardwire kit and stretched it a bit to fit over stud)
Tap the black wire with yellow stripe going to rear view mirror
I chose to route wire out the trim, to do this remove the sunglasses (not too easy)
You can see the two snaps in photo. Release those and it rolls out. There is a wire taped to the top (may be for sun roof I don't have). Under sun glasses folder remove two screws. There are two screws in front too in plain sight (see photo with wire grounding above). Then two gentle snaps on the side and it all comes down easy. Sorry no picture with it all down.
Someone suggested routing over the headliner. You have to snip RJ11 connector to Radar off to do this and crimp on new one. Excess wire fits nicely above sunglasses area. I later ended up doing it this way.
This is what I CALL tidy
Hope this helps someone
