The software routes fine when in truck mode but it does not seem to show any low bridges, width or weight icons on its maps. Is there a way to get these to show on igo? if so how do I go about this

I have igo version 9.6.5.278914 and latest navteq maps installed.

No, not natively anyway, a skin might be able to show them, but if one exists I don't know about it.

Earlier versions of primo used to bring up a warning if you were overweight or approaching a low bridge.
