Hi guys,
stumbled across this great forum whilst pulling my hair out trying to update my maps on my Replacement Head Unit in my BMW E46 M3. The head unit is a Chinese import from Haulingan and it is currently using IGO9, but everytime I go into Nav it says my maps are out of date and I should update at Naviextras.com. However my unit is not listed in the supported devices. Not even sure ...
