Noticed Pioneer now released another GPS navigation app, it's pricey but seems better than NavFree
However, after buying Navigon and TomTom I have to convoke myself spending another 80 Euro's for a navigation app :-\
FYI
TomTom confirmed today to me on Twitter that Appradio support will not be added (read: they are not considering to add it).
Navigon has forwarded the request to an internal team to consider it for one of the upcoming releases.
So I guess we (European users) are stuck to NavFree for navigation, which has some major screen alignment issues on iOS5 :-\
