Nav not working

Nav not working
03 sedan
My navigation isn't working. I started the car today...popped up the navi...and NOTHIN...just a black screen. I turned the car off and then restarted it...still nothing. It was working fine yesterday. There doesn't seem to be any power going to it or the dvd-rom. Is there a fuse for it? Any ideas???

Thanks, I will try that tomorrow...too much rain right now and its 34 degrees outside. I found another thread that showed which fuses affect GPS and Im gonna check those first before doing the 15 minute disconnect. Im wondering though, could it be a fuse if the unit occasionally works? Im guessing perhaps it could be a half-burnt out fuse that is still able to make enough contact to send power through on occasion. Hope I can get this figured out. between the cars gps broken and my samsung galaxy s gps broken, Im getting lost all over the place.

Here is the solution...I posted this up on other site but forgot to update this one....
After taking my dash apart and then the NAVI... I didn't find any loose plugs. But I did notice every time I tap and hit the back of the DVDROM...it would start working...so I wrote down some information off of it and GOOGLE'd it. And I found the EXACT problem that I am having. Not sure if its the same for any of you guys. So now after beatin the crap out of my Navi...it's been working since yesterday morning without any issues. But I do plan on finding someone TECH-savi who knows this stuff to perform this fix. READ LINK BELOW

The problem has been tracked down to a surface mount transistor loosing contact with the circuit board.
The transistor is between 3 coils. A white glue is applied to the coils and also comes into contact with the transistor.
Either by poor soldering or vibration from the coils, the transistor becomes loose.
This board is inside a metal case and is marked:
HAZ 0043
ZSZ1898
This board is soldered to another board marked:
Oop Xanavi Corp
JKZ 1012
IF ANYONE has someone thats able to do this...let a brotha know.

hmm....
My GPS in my 03 coupe also works when it wants to, which is basically never, BUT for some strange reason, whenever it is HOT outside, the gps works! any temp less than 78 degrees or so, and the gps wont function. So now im wondering if the surface mount transistor problem that was mentioned a few posts above is also what I am experiencing. I can picture it not being soldered right, or became loose, and then when its warm maybe it re-melts enough to make contact? I also notice that even though the display stays black, when I first turn the car on it does change slightly to a darker shade of black, which suggests to me that there may be a lack of communication from the dvd system to the display, but the display actually is functioning ok and does recognize when the car is on and power is going to it. I guess one of these days I need to pull it out and take a close look at whats going on inside. Im just not good with stuff like that though....sigh....I guess I should google how to remove the dvd nav system and get started at some point when I have some time off.

In case anyone still has this issue, the good folks in the UK have a nice step-by-step guide to fix it:
http://www.npoc.co.uk/Forum/topic32396.html
That site requires you to sign up, so I will host it temporarily (in semi broken html but good enough)
http://kskucha.github.io/g35_nav_fix/
I will try this out myself this week, will go the soldering route as pushing a transistor in with a screw does not sounds robust.
