OK! I got it! With the stock current ROM I can finally get GPS navigation using Tomtom7 without a cell signal! (tested in airplane mode)
First off I couldn't get the HTC nav tool to work as a primer to tomtom. I couldn't get astrolauncher to work at all.... so I went to
www.visualgps.net and downloaded VisualGpsCE, it is free. Gof mentioned this program above, but I thought he ment something else for sone reason (like he was using a visual gps, like the phone, with tomtom or something, as opposed to just the data...... noob'ness on my part)
I then set Visualgps to com4.
Thanks again to gof, I too found that blue tooth has to be on (on mode tab, check box for "turn blue tooth on" and nothing else filled in or checked. (com manager, options, blue tooth)
Next was a soft reset for good measure
After restart, I turned phone off in comm manager using airplane mode
Next I launched Visualgps, after it got a lock on >3 satelittes I "minimized" using start, today
Last was opening tomtom7 and instant location, poof just like that! I think if u wait for visualgps, its all the waiting u have to do. In my testing, I average 1-3 minutes total, including opening, minimizing, opening etc..
I even tested to see, and I was able to "minimize" tomtom, turn phone on, make a call, put back into airplane mode, maximize tomtom, and I never lost my route! Whooo Hoo thanks gof, and everyone!!
