almanac is not a "connection" it shows, if the card of knowing sats iss written. thats call "almanac". still this gps-postion-map doesn´t exit in the ram of your navi, he can´t calculate where you are. first he need his "almanac = YES".
I hobe i´ve explained it to understand what I mean...

Thanks for your reply mate
but what can i do to fix this problem?

To speed up aquisition of position, your NAV system requires the Almanac to be loaded into NVR. This is basically a course orbital parameter lookup table that says what 'birds' are available and in what position in the sky, for a given date/time. Almanac data is only used for the initial startup to give the system an indication of what birds are in sight and once one is locked, the system will then download the ephemeris data for that particular bird which is a much more accurate and up-to-date table of orbital data.

The Almanac is only valid for a certain length of time and if the position of the GPS has moved significantly since the almanac was loaded, it will have to do a 'sky search' to pick up a good bird to enable an almanac download. Once it has this and can collect sufficient birds with valid ephemeris data, it will be good to provide positioning info.

Now, some GPS systems that require a sky search can take 30 minutes or more to acquire a good bird that is up long enough to download the almanac, so you really need to go to a nice open field with a good view of the sky and horizon (if possible), leave the system powered up for 30 minutes to an hour and in that time, if there is nothing wrong with the system, you will get a good almanac downloaded, from then on things should sort themselves out.

i just arrived home and i did the instructions but it didnt worked
gonna bring it to the dealer tomorrow

i changed the boardcomputer for 400 euro's at a good friend

the dealer sayed 2000 euro's

its working fine now

Do you still have your old one?

no i had to give it to my friend thats why the price was low
but why mate?

I might need an old one for parts someday. Wouldn't want it to go in the scrap
