I've been quite busy with the 06 Crossfire, and this forum has been extremely helpful in getting the last little things taken care of.
The things that I've done today, and over the last two weekends include:
1. Replacing the Siren with a new MB unit from FCP Euro. My car now beeps when using the key!
2. Replacing the valve cover gaskets and resealing the valve cover breather panels with MB sealant. No more burning oil smell.
3. Putting "Karman" brand labels over all the Chrysler logos.
4. Replaced the fuel pump and filter. The car had sat for a decade in old gas, and the fuel pump was weak causing hard starts.
5. Adding a wireless rearview mirror and camera to the back. I used the Boscam K2 from Amazon. Works great and no running wires from the back to the front.
6. Replaces the radio with a Pioneer SPH-10BT. It's a unique radio with a built in phone holder and it's own app. While not perfect, it was $149 from Crutchfield and works great. I did paint the trim ring to match the dash.
