If your Holden Colorado or Trailblazer is stuck with a slow, ageing factory 8″ touchscreen, this solution replaces it without the compromises that usually come with an aftermarket head unit. The factory dash stays exactly as it left the showroom — no trim panels cut, no gaps, no “aftermarket” look. Behind the scenes, we’re swapping in a modern radio and using the iDatalink Maestro APX platform to keep it talking to your vehicle’s original systems.
That means you get a faster, more capable screen while keeping the factory feel your Colorado or Trailblazer was built with — TPMS, steering wheel controls, and vehicle settings menus all continue to work exactly as they should.
Not sure which screen size you’ve got, or driving an earlier colorado RG? Send us your rego or a photo of your dash via our online enquiry form and we’ll confirm fitment before you book.
This isn’t a plug-and-play box — it’s a complete, professionally fitted system built from three parts:
Choose from our CarPlay/Android Auto capable range —Kenwood, Alpine, Pioneer or JVC — and we'll match it to this kit.
Connects your new head unit to the Colorado/Trailblazer's factory systems, unlocking gauges, vehicle info and parking assistance screens while retaining steering wheel controls and voice commands.
Purpose-built mounting hardware and harnessing that lets the new screen sit flush in the factory dash opening — the reason this upgrade looks factory-fitted rather than bolted on.
If your Colorado or Trailblazer has a factory reverse camera, we also fit a VID1 camera adapter as standard where needed — it cleans up the video signal for the new head unit so you’re not left with a blurry or fuzzy reversing image.
No. The APX solution is designed to fit inside the factory dash opening using the correct brackets and harness for your model — there’s no cutting or trimming involved.
No — both are retained. Steering wheel audio controls continue to work as they did from the factory, and your existing reverse camera stays connected (with a signal cleaner fitted where needed for a sharp image).
Yes. This kit is designed to work with a range of iDatalink-compatible head units from Kenwood, Alpine, Pioneer and JVC — we’ll help you pick the right one for your budget and features, including Apple CarPlay or Android Auto if that’s a priority.
It’s built for 2017–2020 Colorado and Trailblazer models fitted with the factory 8″ screen. If you’re not sure which one you’ve got, get in touch and we’ll confirm before booking.
