Like 425, I can only estimate based on the information I have. But if you look at the PDF that was leaked with official docs, *nothing* is required when you select the popular equipment group. It's all optional.
By selecting the popular equipment group, you get this:
PACKAGE CONTENT- 1-YEAR SIRIUS RADIO SERVICE (X9B)
- 276 WATT AMPLIFIER (RD7)
- 6 BOSTON ACOUSTICS SPEAKERS (RC6)
- AUTOMATIC HEADLAMPS (LMG)
- BODY COLOR EXTERIOR MIRRORS (LEP)
- HEATED FRONT SEATS (JPM)
- KEYLESS GO (GX4)
- LEATHER TRIMMED BUCKET SEATS (*RL)
- LUXURY FRONT & REAR FLOOR MATS (CLZ)
- POWER HEATED MIRRORS, FOLD-AWAY (GUK)
- SIRIUS SATELLITE RADIO (RSC) - Sirius Satellite Radio
ELECTRONICS CONVENIENCE GROUP (AFC)
-and-
MYGIG MULTIMEDIA SYSTEM W/NAVIGATION (RER)
are optional.
Though this is just based off the chrysler docs that were leaked. Only a dealer could tell you for sure -- I would definitely PM SRTpusher.
