I have the 2009 Sonata Limited. The power point turns off with the ignition key. That is retarded. Anyone got an idea on how to change this so it has constand power? Reason being, you can charge cell phones and things while at work.

and you want to kill your battery too?

No, I am sorry but to me a power point is something that is supposed to be a source of pwer all the time, so if I want to charge a cellphone or other item I can leave it i the car while I am at work so when I come out it is charged and ready to go and I dont have to have the key on and be in the car babysitting it. In other cars like GM, Ford etc they have constant power, just don't know why Hyundai does things back ****-ward.

If charging a cell phone for 8 hours kills your battery, you've got a whole mess of other problems that need sorting out.

The best way I can think of to solve the problem is to trace the wires from the power point to the interior fuse box, and to find a pair of wires with constant power, then splice onto them.
It'll be a pain in the butt, but should be fairly simple if you have a test light or multimeter.

If you figure out a method Id love to know how as well!

a little OT, but after you turn off the ignition you can still roll up your windows (but you can't close your sunroof :P)

...But, you have to roll up your windows with the car off before you open the door. Once you open the door, you have to turn the car on and roll them back up.

not really a solution to your question but...you could always bring the normal plug-into-the-wall charger and charge them in your office! haha thats my two cents. :gitara:

I'd like a solution to this too. I plug my portable GPS into the power point and I'd like for it to stay on all the time when I'm on a trip. Every time you stop or get gas it shuts off and then you have to re-acquire upon starting up.

My GPS just goes on battery when I turn off.

I gave you guys a solution :P

Figure out where the wires go, then splice them into wires that have constant power.

Silver platter stuff right there... you just need to put some effort in to make it happen.
Even if someone were to "give you a solution" and specifically tell you exactly which wires you need to work on, you would still need to actually make the connections. :whistling:

ditto. i have a tomtom2 and it runs on battery when I shut the car off.

A million years ago, I had a bag phone with a 12V 6Ah battery - charging that would kill your car battery :) , I think I got 2 hours of talk time with it.

Just use the cell to jumpstart the car :)

Somewhere (likely on this forum) I saw a tip.
Likely if you do a search you can find more info.

I've done this and it works great.

Buy 2 "Add-A-Fuse" by Littlefuse
Connect the 2 pigtails together and bridge an always on circuit to the power outlet.

Of course put some thought into tapping into an acceptable circuit and making sure all remains properly fused.
It's reversible in seconds and no cutting original wiring.

Unfortunately the taps aren't cheap though.
In Canada, they are available at Canadian Tire.
