    Looking to Buy '18-'19 Tahoe Engine/Trans questions

    I had a fundamental problem buying a $90k (my MSRP was $89,525) Escalade only to have to clean the TB and MAF on a regular basis. And on top of that I have to put injector cleaner in a brand new vehicle? Now way! And lets not forget that it's a royal PITA to get to the TB. Unacceptable in my...

    Looking to Buy '18-'19 Tahoe Engine/Trans questions

    Exactly... like it was misfiring when at idle... at speed, there were no issues. I was constantly cleaning my throttle body which would, for a short time, take care of the issue. But without fail, it would start idling rough again. I'd swear she ran better after an oil change, but that was...

    Door Handle Locks Work when They Want to...

    I had the same exact problem... mostly on the drivers door, though. I replaced the amplifier antenna and that fixed my issue. See Slupies post, above. $22 bucks from Rockauto and 20 minutes to replace.

    Removable luggage rack - what gives?

    My 2019 Tahoe manual shows the same thing… 220 lbs for the roof rack. You’re looking at the correct thing.

    Looking to Buy '18-'19 Tahoe Engine/Trans questions

    I really can’t answer your questions since I don’t tune and don’t have a lot of miles on my Tahoe. However, I can make a couple of comments on the 5.3 vs the 6.2. I owned a 2018 Cadillac Escalade with 6.2 and 10 speed and I thought they paired very nicely. Shifts we’re smooth as butter...

    New to Me 2019 Tahoe

    Thanks man! Yeah, it's definitely a nice clean truck and I'm really enjoying it! And you guessed it! The Lindsay "special" Blazer Package (special because no one else is doing it LOL) includes all weather floor mats, 2 free oil changes and covers the cost to certify the vehicle as CPO. What...

    What are these parts ?

    I like Mustangs! Here's my 2009 GT. :chewie:

    Looking for a little advice ??

    I'm someone who says "why wait?" And if you're going to wait for MY 2023/2024, maybe you should wait for the redesign that will come out in 2025/2026. Just kidding, of course, but point being, one could wait forever. As for value, like Tahoe14 mentioned, location matters. Your truck here in...

    New to Me 2019 Tahoe

    From your avatar, I can see you're very familiar with the dealership I purchased my truck from. Lindsay Chevrolet. My salesman was great, the buying process itself, not so much. Everything was fine until they told me about their "Blazer Package". What a joke!!!

    New to Me 2019 Tahoe

    I just picked up a CPO 2019 Tahoe Premier with 21k locally here in Northern Virginia for what I think was a pretty good deal considering this crazy car market we’re in. I purchased a 2021 Hyundai Santa Fe in July of last year, but just wasn’t happy with it so traded it for this Tahoe. It was...

    Aftermarket Radio Installation - 2015 Tahoe LS with IO3

    Hi vballrican, I just sent you an email. If I could do it all over again, and had a radio to support engine performance data, I go with the Maestro RR. All the best to you! P.S. - The user guide was taken down due to changes to the hosting site - I'll try to get rehosted somewhere else...

    4.2 to 8in upgrade

    The short answer with regards to doing a swap out is yes. However, you can't simply take the 8" screen and throw it into your truck - that's only one sliver of the pie. In addition to 8" screen, you would need the HMICM (located behind the glove box), radio brain (located at the base of your...

    Aftermarket Radio Installation - 2015 Tahoe LS with IO3

    Haha... I wrote that guide. I'm not sure how you did it, because I tried several times with no joy, but that is FANTASTIC that you got it! Congrats!!! For others looking to do the same thing, can you post exactly how you did it?

    4.2 to 8in upgrade

    Yes, you sure do. The module is the brains of the system... you either have the brains of an IO4 or an IO5/6. ;)

    4.2 to 8in upgrade

    This is very odd. The only way this could happen is if someone upgraded your truck from the 4.2" to the 8" system. Just to make sure we're on the same page, you checked the sticker in your glovebox and you see the IO3 coding?

    Aftermarket Radio Installation - 2015 Tahoe LS with IO3

    Someone on here posted that they were able to splice in their factory camera into their aftermarket radio, but when questioned further on how the accomplished this, they never replied. As far as I’m aware, there’s no way to do this. I ended up installing an aftermarket camera and it worked...

    You have an I03 - third row down, sixth position over.

    4.2 to 8in upgrade

    Pittz - did you by chance add CarPlay? If not, do you know how much it would cost to upgrade to CarPlay? Thanks!

    4.2 to 8in upgrade

    I agree... (even without NAV) thats a really good price!!!

    4.2 to 8in upgrade

    Disregard on the pictures, Pittz. I just found the video Anthony's YouTube channel. This is VERY good news for those wanting to upgrade from the I03 to I05/6 with the factory finish!!!

    4.2 to 8in upgrade

    This is great to hear, Pittz!!! I'm really glad Anthony finally decided to put something together for us I03 owners. Though for me, about two years too late. Question for you - how did you replace the HMI? Or did you have to replace the HMI? And which one did you have to replace - the one...
