I managed to fix this after tinkering around with it for more than 5 mins. I verified date/time and everything was correct. I ended up factory resetting the radio under the settings and that did the trick! I thought for sure that would have been done when the unit was programmed, but apparently not. Anyway I'm up and going now. Thanks for the suggestions guys. Hope this helps someone in the future.

Just got my 2.5 HMI and Radio back from Chis White Auto - installed everything along with the USB plug and now I'm getting this error. Anyone have any ideas? This is on a 2015 GMC Sierra SLT.

Has anyone sent HMI and/or radio modules into dokus for programming? I have some 2017 modules in hand. When I asked him about this, he said he would do it, but his normal process was for you to ship in the modules 1st and THEN he sends you a paypal request for payment (to unlock/program the modules) ... I wondered if anyone had success in doing that, as it seemed sort of sketchy that he wanted the modules sent to him w/no paypal payment prior (as I'd have no recourse of action if he decided to just keep them). Does he have a vetted business that someone can confirm?

Did you replace anything else other than the HMI? What year is your truck?

The p/n do 's exist according to the bilstein website: https://cart.bilsteinus.com/Portals/0/BILSTEINOff-RoadCatalog-2018-WEB.pdf

It's looking promising for the 6112's according to this as well: https://cart.bilsteinus.com/Portals/0/BILSTEINOff-RoadCatalog-2018-WEB.pdf p/n: 47-273702

2.5" level in front on 275/65r20 BFG KO2s (had to ziptie fender liners back and now its 0 rub). I believe in these pix I have stock block in rear but I've since put a 2" block in place of factory 1.25" block.

If you are talking to me the measurements are correct. Pics may be a bit deceiving but it has about 1" of rake.

I ended up with the 275/65-R20 KO2s - got a deal from 4wheel parts I could not pass up. With the 2.5" front leveling kit the fenders measure 39.5" front and 40.5" in rear w/stock block. Before and after:

Looks like a busted upper ball joint. Tough to tell from the pics, as I can't ID that upper control arm- but I wonder if it was one of those 3.5" stretched / level-lift kits?

Got some tires installed today: BFG KO2 275/65-R20 (on 2.5" leveling kit). Fenders measure 40.5" in rear (stock block) and 39.5" in front - In case anyone is wondering.

I would have them check the axles being out of round as well. The wheels/tires could be perfectly balanced but if you have the same issues shown in the vid, you would get the shake you are mentioning.

Thanks guys, keep 'em coming! @Johnv76 How are you liking that setup? Any chance you could post up some fender measurements?

I presently have 2.5" level and trying to decide between BFG KO2s 275/65r20's or 285/65r20's . The latter is significantly more expensive. I've searched quite a bit on here and only found a hand full of guy running 285/65r20s on a 2.5" level. Of the pix I have found, one looks like that setup is "stuffing them in the wheel wells", while the guy running the exact same setup looked perfectly fine. If you have that setup please post up pix! Or if you have the 275/65r20s and wish you had gone bigger, please chime in also!

FYI- A tune from blackbear performance will fix the upshift/downshift garbage software transmission programming from the factory. No dealer will be able to address this.
