we just purchased a 2012 rockwood ultra lite this weekend, beautiful 5th wheel. Havent tried out all the bells and whictles yet, however am very dissapointed in the genesis 3.0. We ciould not get the USB to work nor the SD card. We called the company to find out how to get this running. They told us that the SD card likely wasnt comatible and because there were so many different brands out there thye all would not match. We asked them to tell us which ones do match so we can purchase the right one. The answer we got was "go figure it out". I was very dissapointed with that reply. They must be tested on some kind of SD card I am sure, so why not say which does work, same as the USB, they never did give us a straight answer why it doesnt work. Not a happy camper with the sevice we got on a unit that isnt even used yet! Is anyone else hjaving trouble with the genesis?
