Kills battery life on iPhone 4 and no compass reference

This $89 apps is awful for pedestrian navigation in a city (and yes it has a pedestrian option). the map (2D, 3D or map browsing) requires forward movement to know the direction you are facing instead of referencing the built-in iphone 3GS/4 compass (unlike google maps). So, if you have intermittent GPS signal, you have no idea what direction you are headed. I bought this app so i have my map of spain pre-loaded as not to require roaming data charges of $19USD/MB (you read correctly MB not GB).

the map scrolling and zoom are also terrible. it is not smooth and requires the image to re-build each time you move or zoom. this does not make sense since all the map data is in resident memory (no Edge or 3G required). even google maps is smoother.

Im using this app with latest 1.4.1 update and the battery provided me about half day before completely drained (and this is in airplane mode) and the iPhone 4 feels like a portable heater. I even tried re-booting several times thinking it was a Software hang. you would think that this much energy draw would at least provide seamless compass + GPS navigation. If Tom Toms explanation is "this app is meant for car kit Nav", then why is it sold AND has a menu option for pedestrian Nav?

do not buy!
