I had to reset my device, after installing the app I can not load Tom Tom commercial maps any more, getting error message (invalid key). I used your build in option with email and order ID and got no answer, the SD card containing the files and maps suffered no changes. Please this is urgent. Thank you for your help.
Same issue : after resetting the HTC and reinstalling Navigator I get the "Invalid key" - asking for email address and Order-ID. Unfortunately I don't have a Order-ID as I just downloaded the free version. If I enter my email adress and press OK then it shows "Checking. Please wait" Nothing happens ever after (even not an error message). Please give me a hint or help. Thanks in advance.
thisis somewhhat different problem you are running commercil version, not Navigator FREE go to Start/Programs/Navigator/PC Navigator and select Navigator free
