Customize Your Settings With Toyota’s Techstream Software

By now, you’re likely aware of the features that can be customized on your Highlander via the infotainment system (if not, see your owner’s manual for details). These include a variety of climate and light-related settings, the behavior of your door locks, the height of your liftgate, etc.

But did you know that there are a variety of “secret” settings related to your power windows, moon roof, turn signals, etc. that can only be customized by your dealer? Or by you, if you have access to the right software.

Want to roll the windows down with your remote? Customize the number of flashes when tapping the turn signal? The default is three flashes, but you can set it to five or seven flashes. Etc., etc., etc. Well…

If you take your Highlander to your dealer’s service department, they can plug a diagnostic cable into the OBD2 port, fire up a piece of software called Techstream, and tweak the settings to your liking.

Hopefully they won’t charge you for this service, at least not for initial setup, but… They might. The good news is that you can skip the dealership, as well as any potential fees, by buying your very own copy of the Techstream software, along with the necessary Mini VCI cable.

Where to buy Techstream?

Believe it or not, you can find copies of Techstream + the required cable on Amazon for less than $30 total w/free shipping. That price is so low that I question the legality of the copies that they’re selling, but…

I know of several Highlander owners who have picked up their own copies (and cables) from Amazon and freed themselves from having to rely on the dealership to customize their vehicle’s settings.

What about you? Have you visited the dealer to have any of these “secret” settings changed? Or have you used Techstream to do it yourself? In either case, please share your experience in the comments.

    Watch out for this sort of software deal. I can’t speak to Toyota products, but similar products are also available for Volkswagen products on Amazon and Ebay at steep discounts over official products. Many users at a VW forum (www.passatworld.com) I frequent have complained about viruses and overall functionality of these products. It could be a good deal, don’t get me wrong, but I would use your anti-virus program to scan any disks or files from such sites before installing them on your computer. Just my two cents.

    I’m thinking about getting techstream stuff. I had some questions about it.

    1. What’s the best one.

    Option A)
     VXDIAG VCX NANO for TOYOTA TIS Techstream V10.10.018 Compatible with SAE J2534

    For $ 88 on amazon or something cheaper such as.

    Option B)
    Mini VCI 16 PIN OBD2 Diagnostic Cable for TOYOTA TIS Techstream Cable V9.30.002

    This one is only $22 on amazon.

    2. Is there any danger of updating the software myself such as reflash errors, warranty void, buying it and it not working on Windows 10.

    2. What is the list of features I can update?

    3. How long does it take to update?
