SO I found a MB parts site that lists the module (Siemens 178201826) for $203.70 plus shipping. Is this the SKREEM module? Will it include the antenna ring or is that separate> They do ask for the VIN...but sounds like for parts ID.... at $200 compared to $600 maybe they didnt get the memo...or am I comparing apples to oranges? Mine is fine, but looking for an insurance policy...
