HFP bluetooth echo problem

[CHRIS STARKEY]

Hi, I know the HFP bluetooth adapter isn't supposed to work on Audio 10CD headsets (from early 2004 W203 C class - well it does but with that annoying echo!!)
but is there a way to upgrade the head unit to solve this problem (as it's playing up anyway & needs changing) or any other way of stopping the echo?

cheers
Chris

Apparently the latest HFP cradle doesnt echo on the older cars (it is what another member posted recently on another thread). Ask a dealer if the HFP is firmware updateable, it may fix the problem. If the hardware itself in the latest HFP is different then it probably wont. Dont think the issue it with the headunit itself. Your best of with the ViseeO MB-2 to be honest.
