Any one try the Dice Universal pro install kit. I have an old 2003 G35, no sat button, this looks like a much better solution than typical FM kit. Provides direct connection to FM antenna, and text display via RDS.

How much would have to be taken apart as per the many posts for DD kits to gain access to the antenna
