I would say you're not missing much by not having it. It's not very accurate.

I would strongly recommend getting the rear view camera option if you have the oem nav screen.

I've done it and it makes all the difference backup the big truck.
Thanks for the heads up, Ill test it before i actually go drilling the holes. Ive replaced the mid and radio with an android head unit and a backup camera is pretty simple to incorporate.

I see a lot of OEM hitches for sale that are missing these pieces, and they are nearly impossible to find individually.
Yup, All the pieces other than 1 of the torx bolts that goes vertically above the exhaust tip too retain the bumper. Easy to collect though.

In this case you have to add those previously mentioned bits to your ZCS SA string. You have to add those values to what ever value that bit has. If the sum goes above 10, 10=A, 11=B, 12=C, etc.

Like always start by choosing the profile and read ZCS on either module holding it. I would save the original ZCS somewhere before making any changes.

- After reading ZCS press F1 (Enter ZCS)
- Make changes to ZCS, remove last check digits and check “Calculate check sum”
- F6 (Back)
- F4 (Process ECU)
- Choose propriate control unit (EWS and IKE/KMB hold ZCS), then OK
- F2 job -> ZCS_SCHREIBEN (=Write ZCS)
- F3 (execute job)

Now you have the new ZCS saved code all modules (CODE CAR). Alternatively code (SG_CODIEREN) only LCM, PDC and AHM which in this case are the only modules which have any parameters regarding those added options.
So, i got a chance to check, and after a bit more digging i think i figured it out. So my original values were:
gm 81530080w
sa 2029801100856a0ff
vn 0000007ab72

I then removed the last digit of each line:
gm 81530080
sa 2029801100856a0f
vn 0000007ab7

Then Summed the Bits you mentioned previously:
gm 81530080
sa 202982110085Ea0f
vn 0000007ab7

Selected calculate Checksum and OK, Giving me new values with Check Bits at the end:

GM 81530080W
SA 202982110085EA0F5
VN 0000007AB72

And did not receive and error this time. I didnt realize initially that all 3 lines had a check bit at the end, as does my VIN(FG) which i did not remove during the edit. Does all of that look correct??

Can't say I have any issues with mine - it's been great and I find it very accurate.
