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.

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
