How to get 12 V power ON when engine started?
I want to add a radar detector and a simple navigation GPS to the 2010 C6 coupe (no option except automatic trans) I purchased today (my 2nd Corvette so far).
I would like those 2 devices to turn on when the engine is running and loose power when the engine is turned off. So I checked the 12 V power outlets (ashtray and console bin) and both stay ON always, so i can't use those. When I had a 2004 Z06 I took power from the fuse box on the back of one of the fuse by welding a wire to the fuse on the fused side. Is there a simpler way for my 2010 C6 ?
Question 2.
I was about to spring for an Escort 9500ix like I had before and some simple Garmin navigation GPS. But now I see Escort came out with a combined unit: Escort iQ. The user manual says on page 8 we should disconnect it from the SmartCord when starting the vehicle. The tech guy I called confirmed, which would be an annoyance (prefer to leave it there). I'm tempted to get this radar detector + navGPC combo unit but fear it is too new. And the suction cup may not be a good mount for the hot days in Southern California. I think it just came out a few weeks ago, but has anyone here purchased one yet, how have you mounted it, and do you like it?
Thank you for any advice, I promise I won't bug you with too many mod questions. ;-)

Is this the kind I need? Bussmann BP/HHH ATM Add-A-Fuse
Can I make a mistake and plug it in the wrong way where the positive/red wire coming out would not be fused? Or does that wire only become active after we add a second piggyback fuse? Do I have room in the kick-panel fusebox for that piggyback fuse?
As you see, I don't know much but greatly appreciate your help.

Another way of mounting the radar under the mirror (avoids adhesive): 2009 Corvette With BBE-2006 by BlendMount.
I see myself doing both: Mirror power for the radar, and heated seat add-a-fuse for the GPS.
Thank you again.

I repeated the same measurements with the passenger heated seat fuse: Same thing.
So I can't use either of those 2 fuses on my 2010 Coupe to have switched power. Too bad.
Earlier in the day I called my local Chevy dealer and for $185 they can make my aux power (inside the center console) become switched. I will just do that for the GPS navigation unit.
For the radar detector, I considered the BBE-2006 by BlendMount but I don't like loosing more visibillity under the mirror, I prefer going with the Voztech visor mount on driver side and 8" Invisicord as suggested on Bugman's website.
Thanks guys, I sure appreciate the suggestions, now I know what setup to order.

That works for me, because when I'm traveling(when I'm most likely to be using the Garmin), the Garmin stays on when the car is turned off when I'm getting gas, having lunch, etc, and when I get back into the car and start it, the Garmin requires no action from me, as it's been on during that time the car was off.

So far my options are:
a) Pay my local dealer $185 for then to run a new circuit to the auxiliary power (inside the center console).
b) Draw power from my rearview mirror (see this installation). But then i would have to route a cable around the edge of the windshield to where I want to have my switched power source near the transmission lever.
Other possibilities...
c) I know the heated seat (both driver and passenger) fuses (behind the passenger kick-plate) are always ON (I checked), but maybe another fuse would be switched and I could then do the "add-a-circuit" simple mod. I would need to individually pull each fuse to try to find one where both connector sides are not showing 12V when engine is OFF. Any suggestion on which one may be switched?
d) Can I find a switched power source in the engine bay and route a new circuit through the firewall and to inside the cabin?
e) Is there a wire I can tap into inside the cabin that would offer switched power?
Thanks for helping guys. I'm thinking that if i can't find a simple way, I will just go with expensive option (a). Otherwise, I'm enjoying the new car.

How did you get to that light's positive wire?
Update: I figured out how to remove the glove box light and unhook the connector.
Just wondering now if it will be OK to add an extra 1 A to that circuit: I would connect both my 9500ix radar detector and my Garmin 3750 GPS to it. The GPS alone is claimed to need a max of 10 W (close to 1 A on a 12 V circuit). The wires for that glove box light seem thin.

Thanks to the technician leaving me his printouts, the switched wire to use (pink color I believe) is this one going to the "Body Control Module (BCM) X3" for a 2010 C6 coupe:
Pin: C5
Wire: 0.8 PK
Circuit: 839
Function: Ignition 1 Voltage
Reference documents:
2327181 (BCM description)
2226204 (diagram)
The technician did a neat job by removing the console face plate so he could hide the new lead wire going to the aux power outlet. And he added a 10 A fuse to the new wire, behind the passenger kick panel.
Good rides,
Jerome
