PAC RP5-GM11 Interface & Aftermarket....

Okay, First time listener, first time caller... Sorry just had to. When I get frustrated I handle it with humor.

So, what I have is this issue. I purchased 7" In Dash 7010B from Wish and bench tested power up ✅
Then I ordered the PAC RP5-GM11 Interface. Wired up as instructed. And viola, no power. 
I then searched for NO POWER (PAC) and came upon the Tech Bulletin. Completed those instructions, and NADA. 

I've got nothing. So, yesterday, I contacted service on Wish & Amazon to start over. Have a new/different radio coming, and a new RP5 coming.

Who has successfully wired these RP5's into a suburban? 
Is the selector correct to be on 7(Other)?
Obviously, I am doing something wrong...

Any help would be appreciated.

First thing you need to do is check your wiring. The Chevrolet doesn’t have a accessory power wire in the factory harness. So you have to pull accessory power from the fuse block. You need to wire the accessory wire into a 12v wire that only gets power when the key is turned on.

Yes the setting should have to be on other. The setting would have nothing to do with it getting power. The setting will control if it works or not with the specific brand headunit. Recheck the wiring and go through the PAC manual and make sure everything is right.

Thanks Casey,  I had that "wait a minute" gut feeling. [It has been a few years since I had installed a new head. But I figured still had the technical sense to do it.  This was starting to kick my six. Had to walk away too many times. Will look at that when I get home. Again thanks...

I rechecked everything, except that accessory wire which you just mentioned. As before, I will route that when I get home. Thanks again. Hope this is the culprit. ?‍♂️?

When I installed my Pioneer AVH4000NEX in my truck, I used the RP3-GM11 wiring harness, which worked just fine and provided enough power (10A IIRC) for the radio without needing to run a separate relay/power wire from the battery.  I did screw up and briefly shorted the power wire during testing when the connections weren't wrapped up, and burned a trace on the power circuit board, and after fixing that, it's been working fine for the past 4 years or so.

 

The wiring harness provides both continuous power to retain radio settings, and the main power properly using RAP, and your harness should do the same, you shouldn't need to run any other power wires.  It (at least from what I could tell) responds to the trucks computer commands about RAP, and turns a relay on/off to match for providing power to the radio.

For my PAC-Audio RP3-GM11, the main power relay had a blown trace on the circuit board.  I replaced the trace with a short piece of wire, and it's been working fine since then (about 5 years).

I installed a cheap aftermarket android head unit in my 07 Trailblazer with OnStar no Bose/amp used the RP5-GM11. Got no power from acc wire. I ran a red wire to my Ignition Acc 2 wire since It tapped, I was installing a remote start also. Radio great, but the pac chime does not work and have no steering wheel controls for radio.

I upgraded my Kenwood from 2016 to a 2020 unit of the same series and lost swc w/ my rp5-gm11... I think it needs the firmware update for newer decks.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
