Replacement GPS DVD Unit in HOnda Odyssye 2011

Hi All,

My 2011 Honda Odyssey Touch screen stopped working and so I found a cheap 2nd hand OEM unit from eBay and installed it.

Everything is fine except when I press the NAV button, the GPS doesn't initiate.

I can see that both the old and replacement NAV unit has the slot for the SD Card which I believe is for the GPS?

Any ideas how I can get it to start working?

You may need to do search for Honda GPS downloads and re-load the software (via the SD card ) into the replacement unit
