Jtag Garmin Nuvi 2x5 (MTK Version)

Starting Z3X Jtag Pin Finder...

In Jtag tool:
Warning , you are using <a href="http://easy-jtag.com/?page_id=754">custom pinout config</a> make shure that NRST and GND on proper places!
JTAG Connection is not supported for this device

how can i add this cpu?, i can connec to other models too.
Normally they have a sandisk emmc (SDIN5D2-2G 2GB)
It posible to add read and write emmc byt jtag port?.
Usually almost all garmin gps use CPU ARM7,9 and 11.
Is it possible to configure different sectors in emmc?.

i have a info for sectors of some Garmin gps.

I know it is possible to read the emmc using emmc-tool, but it would be easier for jtag, since the port is the same on almost all Garmin Gps models. So you do not have to look for the emmc points (it usually involves unsoldering the emmc to find them)
