Have had the 535xi for 3 months and love it. No issues. 2 days ago i headed up a relatively steep paved hill at about 25 mph when the car started to vibrate. It felt like the transmission was slipping in and out. Lasted for 20 seconds. I am not sure how to check the transmission oil level as yet so if you can tell me THANK YOU. Appreciate the help.

The radio and cd's sound fine. Dealer blamed the cable connecter but upon swapping with a friend it made no difference. iTunes or downloaded cd's are all that's on the iPod so good sources. Help!

It has two sections that slide back under the interior roof. First section comes forward but second does not. Its like its missing. Must be stuck somehow.
