Traffic will be added soon to both apps as an in-app paid update.
Meanwhile, the U.S. and Canada version has been pulled from the app store. According to the company:
'we found a critical issue in the new update of G-Map US & Canada. In order to protect our current users, we have no choice but to temporarily pull the app from the App Store. We already corrected the problem and re-submitted the G-Map US & Canada for approval. Please allow us a few more weeks to serve you. We will do our best to minimize any inconveniences that might occur to you.'
All the G-Map apps have been reasonably priced, but a bit buggy which has not pleased buyers. I'm working on a holiday buyers guide for nav software for the iPhone, but the whole landscape will change radically if Apple approves the free Google nav app with turn by turn directions and photo realistic rendering of routes. The app is shipping in the new Android 2.0 phones, starting with the Verizon Droid, which is scheduled for release tomorrow.
