This particular unit hasnt been updated to my knowledge... came with the car... :\

Its doing funky things now... burned several different copies of updates, on several different brands of cd's, cheap, mid-range, expencive... :p it takes the cd, starts to spin (screen is blank at all times...) few mins later, pop's the cd out, few seconds later takes the cd back in, and repeats the process, keeps going and going and going...

I read somewhere, sometime used NavCoder, changed region (lang) on the nav after it died, then changed back to US and upgraded to latest firmware, and it worked.. waiting to receive my ibus interface from Rolf Resler... :\
