GPS help needed..

[ImBrowsin]

Didn't know exactly where to put the post for this so i thought i would put it where the most traffic is... I have a Hummbird Fishfinder/GPS with a lot of coordinates.. I want to share them with a close friend but he has a Lowrance unit.. How do I convert the Humminbird formated coordinates to Lowrance formated coordinates... We both have the ability to use an SD card in the units... Any help in pointing me in the right direction would be appreciated... I don't even know what a Lowrance coordinance would look like... Humminbirds read like (N29* 33.017 & W091* 33.563)... Thanks in advance for any help you could provide...
