OK, so I'm very confused here.

I have a 2011 Roadster 2.5.

I've connected a head's up GPS-based speedometer to the 12V accessory port (I'm 6'1" and, between the steering wheel and the glare from the sun, I can see exactly NONE of the 3 speedometers in the car).

The HUD works great...I've installed them in another car of mine. At some point, I plan to hard-wire this sucker in at the fuse panel but, for now, it's hooked to the accessory port. My question is on this 12V port;

It doesn't seem to be switched, or unswitched.

I plug the doo-dadd in, and it's on. I turn the car off...it's still on. I lock the car...it's still on. I look in on the car a few hours later...and it's off.

I can't be 100% sure but, it seemed like it was on 100% for the first few days. Did I drain the 12V accessory battery (I know there's one up front somewhere but, I assume this gets charged by the PEM somehow as the car does its thing)? Maybe it turned off after a while initially, and I just didn't notice (this is possible).

Does anyone think it's a problem leaving something plugged into the accessory port 24/7 (it's a very low-current draw...but haven't measured the exact rate)?

When I unlock the car in the morning, the accessory port comes on (along with the interior light).


Also, quite possibly completely unrelated but, maybe I'm causing my own problem here...so I'll ask along with my original question...Is it just me, or does the range on the key fob absolutely stink? I've checked the battery, and changed the battery, in the key. But, I can only get it to work if I'm standing within about 2 feet of the driver's side door.
