I bought the SB2 at Osh. Had installed it in my pc, but had not converted my account yet from Classic to SB. So I cannot comment on how it works, but it was easy to install. THEN…
Got a unsolicited call from Jepp telling me that they were recalling the SB2 product and gave me a RMA to return mine.
Person did not know what was wrong (just said they were defective), or was not letting on. But I suspect that your delay is associated with this recall. I have not yet received the replacement, although I got a shipping notice saying it shipped early this week.
I thought Jepp was very proactive and cooperative.
