Im looking for a stock Sentra SE-R Spec-V Rockford Fosgate Head Unit, the one with Aux In.
pm me
There is one on the Vboard, not sure if it’s sold or not. Here’s the link:

Don’t know what the Vboard is? If you own a Spec and don’t know, you bettah recognize! 
It’s all about the V and the crazy mofos that drive em. You’ll have to use the above link to check out the ad or register since the frontpage has been hacked and not fixed yet.
Most of the ones I’ve seen on there have gone for $70 U.S. or less.
Thanks a lot! Do you know if the head unit will even work with my car? Im assuming so, but i guess i better make sure before i buy.
There are a bunch of posts about it on the Vboard…sounds like the RF HU WILL fit, and uses the same wire connections as the stock one. The only problem is that with the RF package, the car has an amp in the trunk, whereas the stock stereo does not. So, you might need an amp if you want to add subs and so on.

The nicest thing about the '04 HU is the auxillary in plug…nothing like cruising around with an IPOD with 1800 songs on it!
Oh, the front page works for the VBoard again, so it’s Vboard.com.
Hope this helps!
