Hey guys,

I ordered an MKIV from Bimmernav.com last week. The unit arrived and I instantly swapped it out, upgrading my 2002 X5 and replacing the MK3. After searching a bit for the maps DVD, I went to my local dealer and picked up the 2009 High Maps DVD for the MKIV.

When I inserted the DVD in the nav unit--I get an "error" message or a "no DVD" message. After researching this on this forum, it seems like this is an issue with a faulty laser in the MK4?

When I contacted Bimmernav about this problem, they promptly insisted that I was using the WRONG DVD over and over again until I was forced to actually call Navteq to prove that this DVD I had was in fact the correct one and should work perfectly in the 2006 MKIV computer they had sold me.

At this point--6 days after the purchase from Bimmernav--I requested my money back for the unit and told them I would send back the dead computer. They are refusing to refund me, saying that they are "moving offices." I am not sure how that is much of an excuse but whatever.

Have you guys had any problems with Bimmernav? Any advice for me? This is super frustrating and I cant believe I dropped almost $1k on a dead nav computer, only to get horrible service and an ignored refund policy after the fact.

Any advice or help regarding the navvy problem or the refund problem would be spectacular. THANKS!
