I think you are right, either way thank you very much for all of your help.

Please if any one have this issue before and how I can solve this issue

 

I would check your nav system to ensure it is programmed for the HEV input.

With the key in the Run (3) position, and the nav unit started up (past the welcome screen), press and hold the 3 and 6 buttons. This will take you into the diagnostic mode. Release the 3 and 6 buttons. It starts with a Speaker Walk Test. Press End Test. Next, press Configuration Status. Scroll down to the HEV line; this line should read "[Enabled]," if it doesn't then you may have to have the nav unit reprogrammed by a dealer. I hope this is helpful.

 

Hi,
thank you for info, but did you mean 3 and 6 buttons which is used to select saved chanal or CD when I select media

Kind Regards

 

You are correct, the 3 and 6 buttons across the top of the unit.

 

Good day,

I did it and the configuration gives me that HEV is enabled but the data is still unavailable, is there is any reason for this

Thank you

I think you may have a 2009 or 2010 radio unit in a 2008. The 2008 has a different engine.

 

I am going to ask what is probably an obvious question, but it has not yet been asked: Is the vehicle running? (The green Ready to Drive icon lit on the instrument cluster?) That screen will say "Display Unavailable" is the vehicle isn't running.

If that isn't the cause, what is you H/W version? I noticed a DTC about the Map DVD. Does your navigation function work properly?

You are correct about the different engines, but, as I understand it, all the nav unit uses is fuel consumption and vehicle speed (information comes from the CAN), and the calculation is performed within the unit. So, the different engine theory is not likely the cause.
