Ok i have a 7" LCD that uses composite and of course mp3 and videos are great but when the GPS comes into ply its just way to small to use basiclly.
So what i did was do alot of testing in the car to make the LCD read Destinator on the LCD easily
So what i did was go to C:\PowerLOC\Destinator\Common\Interface\Destinator .Inf and open up the file in notepad
Now move down to neer the end of the file and u will see
::F,Tahoma,24,0
I changed it to ::F,Arial,35,0
Now this the text size of the text in the GPS setting windows so u can see what comport etc you are selecting. It also changed the text in the settings window and the text on the bottom right showing how many sattelites there are.
now right at the start of the file u will see
SIZE=24
change it to 35 or the setting you best want.
This changed the size of most items mostly the button sizes
Now under that you will see these
::T,ABOUT,200,LF,,,24,About
::T,ADDRESS_BOOK,200,LF,,,24,Favourites
thats the size of the text for the buttons like about favourites etc
change the 24 to 35 or a size that suits you

Also note that cause im in australia this was annoying to me:
::T,CITY_STREET,200,LF,,,24,City->Street
Now in australia we dont call it City so i changed it to
::T,CITY_STREET,200,LF,,,24,Suburb->Street
same with
::T,STREET_ZIP_CODE,200,LF,,,24,St.->Zip
We call the Zip code postcode in australia so i changed it to:
::T,STREET_ZIP_CODE,200,LF,,,24,St.->P. Code
makes sense
Now scroll down till u see something like this:
//:

,240,320,639
:

,640,420,640
now i changed the last line to 640 instead of 639
This means at 640 the onscreen keyboard will showup when u search for a street.
Now onto the Sound for destinator
Some people say they can't hear the voice directions over the mp3's play sometimes.
Well what i do is open up the Sound recorder in Start > Programs > Accessories > Entertainment
and i open up the wave files from destinator then i just click the effects button then click increase volume by 25% till you think your happy with it then save it.
Now you can view and hear destinator perfectly
Only problem is the map you cant change the text size of the citys/suburbs but you dont need to bother about it cause i use 3d mode a bit but i also use normal mode and if u wanna know what street your on click the info button for it to tell u as he text is now readable for u
I hope this helps some people till the D3 sdk gets sorted out
Also you could do what iv done and actually changed the button bmp files to match the media car skin
Im also working on a nice media car skin that looks good on a composite LCD

as i dont want to pay $500 for a lilput
Hope this helps some of you guys who are stuck with destinator till we get a new version and i hope it helps make life easier for guys without a VGA screen like me
