Cobra 4000?

I have a cobra 4000 GPS. Its the only one that I have ever owned so I don't have alot to compare to. I do like it and its never let me down. I love the big screen, bigger than most I've seen, which is good for old eyes.
My question is , I don't see any info on this GPS here. Does anyone know if it will work with this map system,and maybe any details that will help me get started? I'm a newbie here and I want to start as a contributer.
Thanks BOB

The least you can do is download the routable 5.08 map and load it to your unit. There is no assurance that it will work but at least you tried. Remember that this is a forum for Garmin compatible maps.
