I purchased the Samsung Navigation Vehicle Mount. Problems: I put my Samsung Fascinate in the dock...it goes to the standard Car Dock app. I don't want that because I want google nav etc. So, I got the Custom Car Dock app. Now, I can't seem to get the Custom Car Dock to launch when I put in dock. Another issue...the audio jack does not work on this car dock. Can someone help me...Ultimately I want a car dock app to launch when in dock showing my custom apps. Also, I want the audio jack to work...any ideas? Thanks.
