With that current fw id say its a version B but whats the whole part no? 1T0 035 680 A,B or C?
I also wouldnt jump from fw1100 to fw38XX id got to fw2760 also if its pre57 you will get battery drain so make sure your gateway is revision L or Higher or run modified fw2760

Hey Nicki,
the Part Number is 1T0 035 680
HW: H74
SW : 0520
i dont see anywhere A or B
thank you
right now i have 1100 on it and still willing to update to new firmware
I think you will need to upgrade in the following order
1100 to 2680 (you can't jump from 1100 to 2760 certainly not in any unit i've ever tried)
2680 to 3XXX firmware
However if you have a B revision then you won't be able to go any higher than 38XX firmware iirc
i just posted the part number of my Device,if i have B version i am still able to have it working with 38XXX,
but when i install the 38XX version on my unite somehow my uniit become nut!!!
when i take the key of the car stays on, and also the lights on the buttons of the radio are always off, and from time to time i have to log the device with the auto with the security key,
Hey guys,
i got RNS 510 with Firmware 1100 /1102
i am willing to update the firmware to the 3X
can you advise how do i know my currently firmware and My untie series ?
have you not answered your own question? 
i am not sure if i can follow you!!!
