alpine cda 9884 , xmdirect2 problem

I purchased the Apline CDA-9884 & XMDirect (CNP2000UC & Alpine adapter) package over the holidays and have had nothing but issues with getting them to operate together.  I first though that the problem was an issue that the exact XMDirect2 firmware for my radio not an exact match.  But, Audiovox recently released a approved firmware for my Alpine and the same problem pursist.

The problem is the XM radio will work (I activated and listen to all the stations ) for around 30 to 45 minutes then the XM will go into a "searching" loop, as displayed on the Alpine face.  All functions lock on the radio are frozen and the only way to get the radio reset is to disconnect the XM tuner to get the radio & CD back.  I tried two separate CNP2000UP with the same results - vendor send a replacement.

I spoke to tech support at AudioVox  and they say that they never a the same problem reported.  I talked to Alpine and they said it is an Audiovox problem. 

I checked and rechecked the connects - I reground the CNP2000UC to metal instead of to the radio connect. 

Am I missing something - hopefully, someone can share a potential solution.  The Audiovox CNP2000UC is the game in town to get XM Radio.

Thanks,

Tom
