[Touch Pro, Fuze General] Sleuth255:
Sorry about the delay: I had to sit on my hands waiting for the site to come back up.

Ok, I have the comparison video completed. It features a 9 minute drive through the outskirts of Milwaukee WI. At the end of the video, I get the car up to about 100 Km/h (60-65MPH) to see if there's any speed related lag differences between the two devices. Here are some things to note/watch for as you view it:

In a nod to those of you who want to see the test run with current fuze navigation software, my Tilt is running TomTom v6.032.8351 and my Fuze is running TomTom v7.450.9028 VGA edition. My Registry polling interval value is at 250 (poll 4 times/second).

BMW speedometers are set at the factory to read faster than actual speed. Why they do this is a subject of intense debate outside of XDA...

There are several points in the video where I say "mark" or "now" when passing a cross-street. These provide the absolute best way to view and make your own conclusions about any differences between what both devices show and what's happening in real-time. In fact, when I last say this towards the end of the video, you will see a reflection of the intersection's street-light flash by at the same moment. Speaking of intersections, at one point I provide a verbal reference to passing through a large, controlled intersection. My reference is made when the car passes by all the side street ramps as well. You will see what I mean when you view the video.

TomTom 6 postion is the center of the indicator and TomTom 7 is the leading point of the indicator. Again, you will see this for yourself during the video. It's easier to measure lag based tracking differences by watching the side streets tracking from top to bottom on each device's respective map. The absolute best time to view any positional syncronizaton between the two devices by using this technique is near the end of the clip where I am jabbering about POIs being a POS in the US while lots of side streets are going by. :)

IMO, "Speed lag" is well documented by this video and occurs on both devices. The fuze is slightly more pronounced.

sorry about taking the camera off the devices to show the speedometer for a few seconds during the high speed run. I wasn't sure if you were going to be able to read the speed on the displays. As it turns out, you can.

IMO, "Position lag" is non-existant or within the boundries of GPS accuracy for each device. In fact, you'll see that the Tilt actually shows the car passing by intersections before I mark them verbally in a few instances. I feel that the fuze has more overall accuraty from a positional perspective. This may be due to its signal strength advantage.

Speaking of this, note how the fuze signal strength compares to the tilt signal strength throughout the entire video. :eek: This persists even when I swap the two device's positions to eliminate any reception hot-spot advantages.

As far as I can see, my own GSM Raphael is a capapable navagator when using its built in GPS. In fact, its every bit as good (IMHO better) than my Kaiser. After viewing the video, I think you will agree that there's no significant positional lag on either device. This is good news for RALPH1000 owners who do have position lag because it means that there's either an already accomplished software fix or an early revision based hardware issue at the root of the lag controversy. CDMA ralphael owners are a different story however since your hardware isn't identical.

Here's the 9 minute clip. Enjoy the ride!

Tilt/Fuze TomTom comparison (Sleuth's on the road investigating lag)

Up next, I test with a ROM/Radio of a poster who reports un-navigatable position lag. If I reproduce the positional lag issue, then (at least one of) XDA developers' awsome ROM chefs have already provided a ROM based fix for GSM raphaels running TomTom v7.450.9028 VGA edition. If I don't get lag then HTC has some 'splaining to do to you older raphael owners... ;)
