Re: Who knows connect navi+ JTAG pinouts?

Great news.

can you please tell me how you do it?

Its good to know what version of hardware you have (ricambi number of your units).Then look for similar unit on this fiat forum, and is better your colleague will known navi code.Then go to the electronics workshop in which repairing car radio and navigation systems.Ask them to copy content of the flash from working unit and re-program with this copied content, flash from your unit.Programming can be done externally on the programmer like Wellon VP-490.I don't know exactly which and how many flashes you have to re-program.If you have 2 memories.One installed on the top, and second installed on the bottom.Is better to copy content of 2 flashes and rewrite 2 flashes (i never did this but would risk).After programming you may need master code from this working unit.There is some version of SW for stilo's as remember 9.8?! which makes unit decoded.In mine CN+ (AR159) code was overwritten and I had to provide master code when inserted the ignition key.Did this only once and working.

whats what I expected. fortunaletly i have a fried with another working unit. Just have to convince him to let me read the flashes from his unit.
what i find in the meanwhile was that the Stilo navigation unit has the JTAG connectiosn on the mainborad, on a missing connecotr (on the left side of the unit.

1- TCK
2- TMS
3- TRST
4- TDO
5- GND
6- TDI
the problem is, witch program should we use to get in the main processor.

JTAG is a great solution but unknown for me so far on connect nav.Do you have any picture which socket?What processor you have on the mainboard?On mine is SH4.Please look on the picture attached.I have white 6 pins port on the left.How you will numerate the pinouts from left to right or right to left.?
