I recently purchased a 2004 Vibe AWD, and I decided to put a JVC unit in my car (

My brother, who I should add wants the 2003, decided to put the factory HU from my 2004 (the standard HU as shown in this photo here:
http://www.hifisoundconnection.com/imag ... mage-1.jpg) into my dad's 2003. The installation went fine and the radio is no longer static noise, which is great!
A few days after installing the unit, I needed to move the car so my brother could clean it out (he doesn't have a license, and I'm 1 of 2 people in the household who can drive stick), but as soon as I put it in reverse, the fan stopped putting out air, the dashboard dials turned off, the cabin beeper for reverse stopped beeping, and the windows were no longer going down. Now with it being 80+ degrees F here, and the car being all black, it was extremely hot inside, so I moved it back into the driveway and left it there for a few days.
A few days later, my dad goes out and sees that the 10 amp fuse that controls the dials, windows, and cabin air was blown, so he replaced it with a new 10 amp fuse. We started it up and it was working again. Until I went to move it again, I didn't even get it all the way in to the reverse gear and everything cut out again.
We have not verified it yet, but we believe the fuse blew again. This all started after my factory HU from the 2004 was installed. My brother has put the original DVD nav HU back, but has not replaced the fuse to test, but we believe this could all be tied to the 2004 HU having a security light on the unit (as seen in the picture linked above, its the little red light under the screen), and the 2003 GT having a security light next to the hatch-window-open button under the mirror controls.
I'm now here today to ask if any of you would have any possible reasons as to why this is happening. From what I've read online, it seems it could also be a short in the circuitry for the reverse lights, but I find it unlikely as this all started after we changed the HU. Let me know what you all think, we're willing to try almost anything to get the 2004 HU installed and working properly in the 2003. Thanks!
