So the ebay vendor is eflow666. His name is Jimmy Chen and his contact information is listed on the ebay listing. He has been repairing BMW, Mercedes and Jaguar nav screens & on-board monitors for over 14 years. For a cost of $200 he will repair an on-board monitor to make it functional again (i.e. if the tape deck no longer works, etc). If it is determined that the LCD panel needs to be replaced, or if you already know that it needs to be replaced and just want a new LCD panel installed, the cost is $270 to replace the panel with a brand new one. His turnaround time is about 3 business days. If you have any questions I suggest you call him with your specific issues and get his recommended fix. BTW, don't bother going through ebay, just deal directly.
