hi, i had this LG CAR GPS

Fabricant: LG

Processeur: MIPS Au1320 667 MHz
Mémoire vive: 256MB DDR2
Mémoire flash: 4GB

wich version updated of igo for this GPS working, i have tried a lot of Win CE igo primo, and nextgen, no one works, 'Problem not Work for this WinCE"
i use igo primo 8.3.2 dated 2009 Working but old version... is this caused by MMIPS PRocessor not ARM ?

any link to igo MMIPS Version .?
thanks for response
