The interior fuse box is actually the BCM (Body Control Module). There are several pictures on this forum and a table of what each fuse position is, at least from one old and no longer available online wiring diagram.

What do you want to do with the fuse position(s)? The BCM has programmable modules and its fuse positions may or may not meet your need, or they may change their properties after a flash. If you identify what you want to do, someone may recommend a better source of power.

I just need to take a certain fuse out F53 which is for the USB/AUX port. I need to confirm the correct fuse. I know its a brown 7.5 amp fuse, just not sure what position its in.

When you look at the fuses from the drivers seat (left) F53 is the bottom fuse in the left column of fuses. According to the owner's manual it is called "UCI Port (USB & AUX)".
I have another picture that calls it "INSTRUMENT CLUSTER ICS (UPPER & LOWER)"
Finally found some COOPER Bussmann ATR Add-A-Circuit 2-10A Fusible taps. PN BP-HHTR-RP.

Alright that's the one I took out, but is it normal for the auxiliary to still connect even if the fuse is out? I took an auxiliary cord and plugged it in and it still connected. The whole reason why I have had to take out this fuse is because something is wrong with my auxiliary. If i plug into it and then plug the other end into my iPhone or iPod it doesnt work but the strange thing is when there is no cord plugged into the auxiliary port and i am listening to music on the radio or off my phone through bluetooth it will constantly connect to auxiliary even though there is nothing plugged into the port.

The F53 fuse powers the Media Port which is the unit that contains the AUX and other ports. That device contains a lamp driver and circuits going back to the radio including Aux Audio Left, Aux Audio Right, Aux Audio Reference, and Aux Connection Detect. Doubt anyone here knows the voodoo behind this device. There is a very expensive MIT019 tester used to check the Media Port's functions. Maybe dealers have that on hand. My SWAG (scientific wild a$$ guess) is the Aux Connection Detect wire tells the radio if something is plugged in or not (i.e. open or closed) independent of power to the Media Port device.

My suggestion would be to check for anything lodged in the AUX port that may be causing the radio to think something is plugged into the AUX port when there isn't. Some of us bought tiny rubber plugs off eBay (typically used in PCs) just because those ports are easily infiltrated by dust and dirt.

As a shot in the dark, how does the head unit react when you touch Media and then select something other than AUX like USB, Bluetooth or SD? Just thinking that may give a clue, but not sure.

It depends. Sometimes it can be really finnicky, and if i press media and press bluetooth it will connect to bluetooth and stay on bluetooth. Some days if i press media, and press bluetooth it will switch over to AUX by itself, or it will switch back to the radio all by itself. Sometimes the AUX option will be lit up when i press media and available or other times it wont be lit up and wont be available.

Ok. Sounds like an intermittent problem. Here are some suggestions in the order I would address them; keeping in mind I don't know anything about this system.

- If within bumper-to-bumper factory warranty, take it to dealer.
- If under an extended warranty that covers this problem, take it to dealer.
- Find out from dealer how much it costs to diagnose/fix problem.
- If too much, remove Media Port and Head Unit to check connections and resistances on lines between them: should be below 5 ohms.
- If Ok, inspect AUX port for damaged/dirty prongs and repair if possible.
- Purchase another Media Port at a salvage yard and install.

In reality, I'd have the dealer fix it because I have a Mopar extended warranty.

Alright thanks for the help. Is it possible to have somewhere replace the AUX port itself?

Don't know. Probably not. However, the Media Hub can be serviced separate from the radio.
