The file you have hosted early in the thread for the 2015 is "MY15_RA4_16_16_13" even though the link says 16.13.13. I think the version is actually 16.16.13 and that's why the radio shows that. If he got the file from this thread, then that's the version he got.
It looks to me like he has a 2015 radio that's reporting a 2016 part number. Most likely they swapped in a component that holds the model number from a 2016 radio. My bet is that there is a protected section of the flash storage that is written during production and isn't modified by the bootloader later on. This is pretty common and typically contains things like model/serial numbers.
v16.13.13 (2013-2014 Ra4 Fw) - most current
v15.17.5 (2015 ra4 fw) - previous version
v16.16.13 (2015 ra4 fw) - most current
v16.09.09 (2016 ra4 fw) - most current
EDIT: (Corrected post & fw version info)
v16.16.13 (Jrg18's Ra4)
I went back through my VIN list, posts 2-5, and the uConnect site to verify the current Fw files...
First off:
- @Jrg18, sorry for the confusion on the FW versions.
v16.16.13 is the correct & latest version for 2015/My15 RA4 radios.
- @00R/T, thank you for pointing out the discrepancy. I apparently missed the typo in post 4 when moving between the posts, but I at least had the correct file/download link.
- @SitKneelBend, thank you for catching that Jrg18's screenshot showed the later FW version otherwise we would not have been looking for the typo.
2nd:
@Jrg18, while we have resolved what the correct/latest 2015 RA4 fw version should be, we still don't know why your radio menu lists a 2016 RA4 PN and yet it seems that you, in fact, have a 2015 RA4 radio.
As 00R/T and you have suggested, it seems that your radio may have refurbished components in it from a 2016 Radio that stored the previous PN.
We will be waiting to see what PN sticker is on the back of the radio (if any at all).
