🔌 Optimized Plug and Play T-Harness for TO2 Toyota Vehicles: Maestro HRN-RR-TO2 Review

Incomplete arrived two seat belts that should be there. This is the second time this seller has screwed up shipping. From now on I will contact the manufacturer directly.

You think after 2 tries Amazon gets it right but no. Both times they sent a Ford wiring harness. Don't worry about the order. Just seek out a false advertising attorney :) Word to the wise

Received an open box with missing wires. For the price it's not something I have to reckon with. Buyers should be aware that you may be in the same situation.

Bought all connections made removed old radio and went to hook up but wiring harnesses are all wrong. Maestro advised me to buy T01 instead. I wish this was documented somewhere so I don't waste my money! BEWARE!

Worked great. If you are buying an aftermarket radio this is all you need plus factory adapters and adapters for a clean install. It is still possible to tweak some factory settings, but not everything works 100% except for the steering wheel controls.

Steering wheel volume control only works sometimes, probably only 50/50 times, same annoying. Other than that, it's a fantastic block.

Not entirely plug and play - lots of soldering to connect this harness to the stereo harness as expected but could be easier. The sticking point was the connector, which didn't match my factory wiring harness, requiring a cut in the wiring harness and soldering in the dash. Not many other options, you're stuck with what you have.

Volume control on steering wheel only works sometimes, probably only 50/50 of the time which is annoying is the one I took off my Kenwood stereo to check and redo the wires one by one, still the same. Other than that, it's a fantastic block.

I used this in a 2014 Toyota Tundra Double Cab. At the same time I replaced the head unit with a Pioneer AVH-2300NEX. Installation was pretty easy, but you'll need to make all the wired connections (although that's expected). The kit comes with an adapter to connect to a USB port, although it is not shown in the photo. Incidentally, the adapter for the antenna is not included in the scope of delivery and must therefore be purchased separately.

Now that all is said and done I love using the idatalink maestro RR despite the complexity of the installation, Set up programming and pairing . That being said, this wiring harness is a mess and largely incompatible with non-JBL 2013-2014 Rav4s and possibly some 2015 models as well. Before I go into what has been explicitly and intentionally left out, it is important to know - for all vehicles - that this is not a full interface. None of the vehicles are equipped with: GPS antenna, radio…
