This is Such an Easy Hack !
If You have Your I-Opener Mounted Moble ???
& Moble Power Supply ???
( I ran mine for a few days on Straight Cig Lighter Plug) No Sound from sound chip)
@ CompUSA I picked up (stock #274570)($99)
"RAND McNALLY STREETFINDER|GPS for LapTop PCs"
includes "DELUXE STREETFINDER 2000" (3 CDs)
(Yea, this is win98se Stuff) AnyHow,
the extra Serial Port is CN12, If you open your "Memory Hatch", it is the 10 pins you see on the Right.
The Trick is to have a Spare? laptop connector, & remove the contacts at positions 11 & 12,
then Cut it to be a 10 postition connector.
Next You need a chip ! I got a MAX232CPE (JIM-PAK) I used the "PREFECT MOD"
this took 5 small caps besides the chip,
But I used "Point to Point Wiring" with the Chip as the terminal strip, added caps and wires, <1" to 10 pin connector,
& 1" from the chip I tied a knot in the cord to the GPS,
Did, I mention it is only 4 wires. (TX, RX, 5V, GRN)((No need to wire CTS/RTS signals)
Notch in "Memory Hatch Cover" (bottom left, between 2 of the 3 fingers)
With DREMEL CutOff Wheel, Grind metal toward plastic. Metal is Very Thin, You need plastic backing it up.
I Wraped everything in Electrical Tape.
Open the Hatch (Observe Pin 1) Plug it in, Close Hatch It all fits in there.
Start with Chip.
4 wires from GPS
4 wires from 10 pin connector (laptop IDE Cut Down)
Oh Yea, You have to Install the Software !!!
just copy the local maps You want including the State Folders, & You don't have to deal with the demand to copy from CDs.
ENJOY * StarFish *
Oh, you got to do the Audio Hack (using the TL082 Op AMP)
(there are 2 Surface mount points You got to Solder to (both are to the side of resistors ), But it is Well Worth It.
You will be Impressed with what this Thing can Put Out !!! MP3s RULE !
MANY THANKS to EveryOne Who Helped Me with this Project.
& don't let me Forget the WebSurfer Keyboard Mod !!! What a Sweet WireLess Keyboard / Mouse.
