I am in the market for a new Nav Unit. I have the 2006 Model 300, but my CD/cd changer stopped working. I took it to the dealer and it seems parts and labor is going to run me $300. I did a quick search on eBay and noticed not only is the New version of the nav cheaper, but it is touch screen AND it has a built in HD. ....then i saw that it only fits 07/08. Has anyone been able to get it into their 05/06 are there any special bezels mounts needed to accomplish this? Has this been discussed before?
