Bluetooth with Mercedes Benz C300 - Echo Problems

Just got a c300 myself... while going thru MB's website for information about phone compatibility, I came across this which may help you a bit:

good luck1

I have new C350 and had the same problem with my iphone. I played around with the setting on the transmission and reception levels in the car. I made reception -2 and transmission 0. I then made sure the volume on the actual iphone (when on a call with bluetooth) was all the way up. This fixed the issue. I think you just have to fiddle with it to figure out what works for you.

There is actually a fix now that they can do at the dealership. I was having the issue and brought it in.. they new about it right away and said there was a bulletin out on the issue to the dealerships. They had to upgrade some software.. so far no more issues.

I just purchased the handsfree MBZ bluetooth for my Iphone for my E350, 2007 model, and it immediately synced my contact list from A-P, then never went beyond that. I have 1600 contacts, but I made a separate group on my Iphone of 485 contacts, but I don't think the remote system can integrate that smaller list.
The remote only seems to sync the entire list. If anyone has had a similar
problem or knows how to solve this one, I'd appreciate hearing from you.

Thanks.

I purchased my c300 in December '07, I never had any trouble with my original iPhone, until my new purchase iPhone 3G - terrible echo, people can not understand what I'm saying - very bad, This issue is mentioned in a few other threads too. Anyone here have the new 3G?

On my 08 with the BT paired, I now am getting dupplicate entries which carry back to the Iphone 3G. this has become very frustrating and went to the dealer who says there is no issue, but I do see an issue with the iphone as to why the cntacts list get doubled in it too.

Anyone else get a dealership update on their Mercedes C300 software? My 2008 C300 works great with original iPhone except address book doesn't sync. Also, has ANYONE had success with 3G in a 2008 C300? I would like to upgrade but have not read any message where a 3G has worked with a C300. thanks, ralph

I got my 3G yesterday and it paired right away with my 2008 Mercedes C300. No problem. I first deleted my old BT profile on the C300 for my original iPhone and then set up the 3G as a new BT profile. No echo problem on either end. I love it.

Same exact problem. The suggestions in the article do not help.

Anyone else?

I can not even pair it on my C300 2008.
