This topic has been raised b4. I was able to get the 05 Navigation system including wiring harness for ~$760 from Ebay shipped. I have an 05 LX and wants to put the nav in it. I know I will need to buy the upper vent with display panel and probably the mouting bracket for the DVD-ROM in the trunk. So will this be plug and play? I guess not...what do I need to do to get the dual climate climate control since I don't mine is manual. I know there's a sunlight sensor on the dash and one on the driver side...So I will need to buy those sensors...are these sensors plug-and-play once installed. Any help would be appreciated. Thanks.
