I want to thank the Maxima.org community once again. I have a 2004 Maxima SL in which I had my car prewired for satellite. Well I went to my dealer to see how much the unit would cost and they told me $533.00. My eyes almost popped out of my head. I told them they were crazy! I read on these forums that Grubbs Performance Parts was running a special which I was able to get it for $260.00!! Since I wasn't aware of how to install I searched around these forums and found out it was easy.

1) Place tape on back of Clarion Sirius Unit drill two holes and mount in trunk
2) Connect harness to back of the unit.
3) Coil antenna (I mounted mine in the back in between the speakers

Thats it! I was done! For $260!!! A savings of over $260 dollars!!!

Thank you all!!
