Hi Guys,
i have a MTK GPS which was one of the first ones available (still has the external battery on the board) and as far as i have understood, i need to update it to 1.6, in order for it to work with AC2, correct?
Now, i did everything as instructed in the Update-Wiki: http://code.google.com/p/arducopter/wiki/MediaTek
However, I haven't got a FTDI cable, but I have got a FTDI Breakout Board from Sparkfun (this one: http://www.sparkfun.com/products/9716)
What i did, i hooked up on the Breakout Board -> GPS:
GND -> GND
3V3 -> 5V
TXO -> OUT
RXI -> IN
Is this lineup correct?
When i attached it, the GPS light up, the Blue LED was pulsing slowly.
Now i did everything else as described in the manual(right comport is selected, right Baudrate and so on), but when i upload the code, i recieve this message:
[Flash Download]
Fail!!(Download) BROM_CMD_START_FAIL
[Finish]
Take(6) secs to test.
Can someone please tell me what i am doing wrong?
Regards
Daniel

Well, with great help from Darren in the DIYDrones-Chat (thanks a lot for all your patience and great ideas! ) i have solved it.
Basically the cables were wrong,
TX0 -> IN
RXI -> OUT
is correct.
We first checked if i could get a fix using the program Mini-GPS. (for my old GPS it needed version 1.3 from here: http://www.rcgroups.com/forums/attachment.php?attachmentid=3246424 )...
then i could play around with the cables and when i got fix i knew i could now update it, which worked perfectly with the advice from the wiki link up the top!
Then another test with mini gps, after the update version 1.3 doesn't work, so i used 1.4 from here: http://www.4dsystems.com.au/downloads/Software/GPS-Tool/
All works fine!
Only one question, it is 2:55 pm here where i am, the gps in mini-gps states it is 12:55pm, why is it off?
Regards and thanks again Darren!
