Thanks,

I went to ebay, thinking of getting a Pioneer DEH-1400…

It comes with the plastic trim and the wire harness, isn’t that all I need?
It's an older model so they won’t say at Crutchfield if it fits the Sol or not, but the newer version fits, so I guess this one will too…
I thought the installation is straightforward, not so?

They also have Honda receiver installation kits at Best Buy, what about those?
