honda crv sat nav error?

Please can anyone help me with my sat nav on my 2004 honda crv, it says dvd error and I have tried a friends dvd disk in there but it has the same problem. I have tried going to the force download screen but nothing happens and on the diags screen it says everything is ok. Are there anymore reset procedures and also is the unit easy to take out of dash to inspect. Thanks.

Following an exhaustive test drive trying to trick the system, I can report it's never worked so quickly, especially when I deviated from the route.
What used to take a minute is now a couple of seconds!

Thanks again Bartley!

I found the above question but can't find the answer.
