I'm swapping out my stock head unit for a new Pioneer and was thinking about installing a SoundGate STARMOD2 to keep the On star (at a later date) I would like some feed back from anyone who has install one. Install tips, location of install etc.

 

 

Thanks,

Well, I have been patiently waiting a reply to your post as I have the same question. Called Soundgate directly, the rep was stating what an easy install it was when he asked whether I was an installer/dealer. Upon finding out that I was not he changed his tune - it was now a very complex and highly technical install w a lot of problems. He would not sell product directly and referred me to a dealer.

 

It seems to me that it shouldn't be that difficult.

I also called Soundgate in Wyoming and talked to some a**hole there, once I told him it was a self install, his tone changed completely " Oh its so technical- you should have a pro installer do it" - ya know, blah, blah, blah. But he got real quite when I told him I'm a wire systems engineer! I think I can handle this one! It's maybe ten wires total. So I ended up ordering a "starmod2" from the internet. I let you know how it goes after the install, if you would like. Which should be this weekend.

Well, I installed the Starmod2 v2 (version 2) this weekend and now my Onstar is working again! Installation went fairly well for the most part considering this was the first time thing for me. I hooked up the module to a Pioneer CD reciever model DEH-P47DH. This particular head unit has a mute input lead with a negative "trip" which simply means that the mute will enable anytime the trip lead is grounded. What I learned before installing the Starmod is that the mute output signal from the Starmod interface is a 12 volt + and cannot be connected directly to the head unit. The way to connect the + output trip signal is through a relay. The instructions included with the module contains a wiring diagram using a Bosch relay in parallel with a 4001 diode. Basically what this breaks down to  is a Bosch relay socket and a matching "flasher" relay. This accomplishes the necessary grounding action to ground the mute circuit on the head unit anytime power is applied to the Starmod via the Onstar buttons. One good thing about the Starmod module is that its amplifier is able to drive two small speakers connected as a 8 ohm load. The unit even has a gain adjustment to control volume level to the speakers. This arrangement doesn't work as smoothly as the factory electronics but is good enough for the system to function. A small problem I have to fix is the tendecy for the speakers connected to the Starmod to "pop" when the lights come on when entering the vehicle. I think it could be a filter type problem.

how did you connect the Starmod highlevel wire or RCAs. do have an amp for your speakers or from radio to speakers??

 

The best thing to do with Starmod is to isolate any output signals away from the main reciever circuits. Although you are able to connect into the reciever speaker circuits, I thought it was best to wire the speaker outputs separately in order to prelclude any signal feedback issues. Either from the reciever amp or external amp(s). The two speakers can be wired directly from the Starmod unit in series as a 8 ohm load (4+4). Because it has its own amplifier. My setup solution is as follows; the Pioneer head unit drives the rear door 4" x 6" Infinity ref speakers only, I have a 200W amp to drive the front Infinity component speakers. I removed the factory tweeter from the door grill and placed the component tweeters in the "sail" panel as surface mounts. I also mounted the crossovers inside the door behind and below the 6.5" door speakers with 3M tape. I then enlarged the vacated factory speaker location to accept 3.5" Kenwood paper cone speakers for the Onstar/Starmod circuitry.  This arrangement now leaves me with the ability to drive some 4" speakers in the kick panel area driven off the unused channels on the reciever.

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...

      Different requirements for oil filters?

      // Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response- glenn

      Alternate wiring for Kicker sub with Bose system. (DO THIS)

      By smooth68 · Posted

      I started my install this weekend. Everything was pretty straight forward but I ran into one issue with running power through the firewall. The nipple grommet on my High Country already has a small harness running through it - has anyone else ran into this issue? And on the engine bay side, does the wire basically just penetrate the factory wiring boot? I did this on my '22 Trail Boss and it seems much easier but thats been a few years. My other thought would be possibly drilling a new hole adding a rubber grommet just to the lower left of the factory hole. Thoughts?   Has anyone used a T-harness off the Bose amp and obtained power from there? It seems a little odd that such a small amp needs 3 power leads

      By glenn27 · Posted

      ///// Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly. I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere- He gets s  good discount because of volume bought. Anyway-Thank you -Sir for your response.   glenn
