Bluetooth GPS sender
EN
Here is the story: I use my cellphone as GPS navigation unit most of the time in my car and unfortunately it GPS chip do not get so fast satellite coverage, or either I need to turn on the 4G network on for fast location.
As “bonus” the back of the phone get hot. Also, sometimes due the navigation process and heat from the car vents phone get fast hot and start loose control.
Next, I try to use my old Nokia LD4W Bluetooth unit and via right GPS sender app my android phone start to work better.
After that, seems become dependent of the battery of that Nokia unit so I bought few parts and create “proper” car GPS sender.

VCDS 18 - china clone some fix
EN
You can find plenty information in internet how actually to convert some old VAG cable with Atmel inner IC components into modern version. My problem was, that after ordering one clone from china it start only one time and that was it…
After digging and finding the needed FTD firmware, I try to fix that not running state but it was not possible.
What I mean is, that the FTD programming software see the 93C46 memory as.. blank. I can connect the cable, see it as FTD serial device but that`s all. After I select the right firmware, push - write, it been claimed that software wrote all bytes and after pulling the cable and plug it again.. it is exactly the same..
So, I open the cable and decide to remove the chip.

EN
What is the story? Mate, have that Labtec set, but want to use only the woofer. Well, first was almost sure can be done fast and easy with some cut and glue.. but.. was wrong. Without the first board didn`t manage to make the second one to work.
For the purpose I cut the cables, and same time the tracks from the mainboard plug to the rest of the board. Then measure what color goes where.
