But the fact that you are still waiting when there have been others with the same/similar problem that have gotten replacement parts tells me that there is more to the issue.

If the system can survive DBAX ( Click Here for example ) and the system is on another vehicle now still going strong, that says alot.

I am not saying its perfect because I have seen a few fail and others just hammered to HELL that have not, but god you have got to get over it and get a solution. Call em up, find another solution, buy another system or sell the X.
