Unfortunately, it's incredibly hard to troubleshoot issues online without being able to run tests of any sort, especially when it comes to third-party solid-state components that can't really be opened or anything.
This Mercedes SL-Class Workshop Repair And Service Manual will surely help to test fuses, remove the sat nav and eliminate potential external culprits, but if there's a problem with the sat nav itself, you'll probably need to give your dealer a call. Just like the radio or ECM, for instance, manufacturers rarely include information on how to open them and test the internal circuits — the procedure usually recommends just replacing the whole thing altogether...
Yes, it's a bummer, I know...
