reading the responses to your perfectly legitimate questions illustrates perfectly why maemo is an evolutionary dead end. people can find the time to post useless responses or complaints about reading earlier posts but not provide info/links.

wish i could help you my friend but i gave up on ovi maps ages ago. and now that my usb port is broken i cant charge the n900 in the car so battery sapping satnav is a non starter.

my advice to you would be - get an android phone.

and dont ever dare ask a question that may have been asked previously (and never criticise the posters that criticise you) it's not like this is supposed to be a community based forum after all is it!?
