Well, I just joined you other TC owners and picked up a Black Cherry TC on Thursday.

After much searching and reading on this and a couple other scion forums I figured out the following:

1. I need to get a new head unit so I can still use my same xm reciever/tuner from previous car as well as have rca outs for my sub and more EQ flexibility.

2. The Hornet 727T appears to be the best option to be able to use factory remote with an aftermarket alarm.

I pulled the xm reciever/tuner etc along with the amp/sub from my old car and have the Hornet and new Pioneer DEH-P4800MP HU and dash/wiring kit on the way but I really would prefer to have a good installer put it all in.

Franks in Berkeley is the only shop I've talked to so far so far that really seemed to know what they were doing but they are seriously pricey.

Any other suggestions?

Thanks
