My Ride: 2004 325i
Cool 2004 325i OEM NAV Retrofit problems!

Hello- I am have gathered through quite a bit of research that in order to replace the HK business cd / stereo currently in my 2004 325i with factory BMW NAV / DVD, I need to relocate the climate control panel from its current location below the radio, to just above the ashtray which is a piece of cake, but the cheapest I've found the relocation bracket (that contours to the curvature in the hvac panel as opposed to the square edges of the storage compartment currently occupying that space) for is 90$. I obviously need to buy the NAV DVD system itself which is pretty much an all day every day price of 600$. That much I am fully aware of and capable of doing quite easily. I have disassembled the stereo / hvac panel and center console twice now, and I am confident with that portion of the retrofit. Where I am confused is on whether I will need a new wiring harness, and if so, what is nescesscary to install that? The NAV unit is listed as a plug and play item, or am I just being optimistically naive in assuming the seller would disclose the need for a 400$ wiring harness for retrofit application. If there is anybody out there who has done this b4, any advice would be much appreciated. Thanks-
