Any updates on this issue? I have had this intermitted "issue" for over a year.

It will work fine for weeks and then for a couple days not aquire the sats and have the same data errors. I replacement my antenna to no availe.

I have on 04 325ci that's out of warranty and CPO doesn't cover it, so I am on my own!

I am wondering if I should try and replace the Trimble unit inside the DVD drive. I have opened it up and reseated everything.
