DVD navs are different and appeared in the 2006 model year. They used regular speaker out to run the a conventional analog amp.
2004-2005 CD navs were 100% digital. The digital out was ran to a digital amp that ran the speakers.
Not all V10's had the Nav installed, but most were loaded, so most did.
If you have the red MFI display, you did not have the Nav system from the factory.
There were 3 ways to have the color MFI.
1. You had Air Suspension.
2. You had NAV.
3. You had both.
So, even having the color MFI did not guarantee that you had the Nav system.
You could recode the CD Nav unit to do analog speaker out, so it was possible to retrofit the Nav into a 2004 that came with the radio. You could put it into a unit that had the regular radio installed, but you had to do some wiring as the regular radio and the cd nav used different electrical plugs.
As far as I knew, 100% of the nav systems in 2004-2005 were shipped with the speaker out disabled. Once again, they did digital out to run a digital amp in the rear cargo area. There was a 10 vs 11 speaker system, so it is possible that there was a difference that I was not aware of.
Find the build sheet for your V10. We can decipher the codes and tell you 100% what options were factory installed. You can find one copy in the original manual and there is one copy located in the rear spare tire area.
The dealer can also do a build sheet from your VIN.
Also, the parts department can enter your VIN number at the dealership. They should be able to quickly tell you what the radio was factory installed. They should be able to tell you if an amp was installed also and give you the part number for that amp.
When they give you prices, you can just say "Wow! I will to think about that. It will be expensive.
