Thread: iGuidance 3.0 UMPC and RoadRunner n00b issues

I think I know of why.

The way that iG redraws is not double buffered. That is the only explanation I can think of.

Meaning most programs display 1 image, and then do all the calculations for and draw image #2 "behind" it but really just in a buffer. The it "flips" the screen so that the entire new drawn image #2 replaces image #1 all at once. And then the new image #3 is drawn behind again and it flips and so and so forth. This is being double buffered.

iG seems to not do this. Instead it draws image #1, then clears the screen, draws image #2 directly to the screen, clears the screen, draws image #3 directly to the screen and like that. The clear function will automatically wipe the screen to a set colour (white in this case), and then it draws over it.

So on slower machines, it seems as if the cleared screen shows too long when making a drastic change in the screen. I tried on my home PC, and the white screen was non-existant. Ran it virtually and kept slowing down the processor and the white screen became longer and longer.

So I think that the only solution is a faster system unfortuneatly since we cannot change the redraw feature of iG...

No update on speaking st names? I really want to use IGuidance since I have a copy of it already, but I might have to find a new solution if it can't do text-to-speech.

iGuidance 4 does TTS. Also there was a program someone was working on that took the little bar with a streetname as an image and tried to render it to text and then to speech but I think it was canceled because version 4 it is native.

When did version 4 come out?

IMO, iGuidance4 is awesome. the UMPC/carPC version is made for small touchscreen monitors, so it looks and works great on a carputer. it has 'virtual' buttons big enough to safely touch while driving.

it speaks out every street name, not just major highways. I use IG4 with the BU-353 GPS mouse and it works great, it already has a position fixed before my computer finishes booting up.

IG4 still suffers from the 'white screen flash'... but it appears that this only happens on slower machines (like my 650MHz PIII). it is annoying, but it's not enough to make me not use the program. I'll just have to deal with it until I install a faster machine to run it.

you can't download it. you have to order the DVD from iNAV or an authorized reseller like buygpsnow. the DVD comes with 3 versions (laptop, UMPC/carPC, and PPC) and it allows you to activate and use 2 versions at the same time (I use the carPC and PPC versions)

I'll have to look into that. Are the maps updated too?

The maps are updated too. I believe there is a trial version now too :-)
