Adding Voice Module to 03 C320
Hi, I am in the process of upgrading my C320. I bought a Voice Control Module, fiber cable, and PTT Stalk recently. I installed it in the trunk but it isn't recognized. Is it safe to assume that a trip to the dealer to update the computer system is required? It did not come with instructions. I installed it based on what I learned on the forums and the internet. My next purchases are going to be a US Comand with Sat button and an Argo bluetooth module. I already have the Sirius module sitting in a box waiting. I hope a dealer visit isn't required because I will never set foot in the local dealership again. There are a couple shops an hours drive away though. My B service is due in abut 6000 miles, perhaps I'll do it then. By the way, while this is my first post, I find the information this forum and it's members offer very helpful and entertaining.

2004 C320 pewter/charcoal
I have a 04 C320. Bought the voice module, stalk, hands-free phone system (actually off of ebay) I believe from an '02 (not sure which model). Originally the dealer said it couldn't be done. I insisted they try and they did install it (was a bit pricey for install, I forgot but think it was in the $500-700 range). Does work like a charm and was a great mod (voice recognition for saying phone #'s is especially great (and safe while driving) plus you can have your address book voice recognized too).
