Dongar Pro+ works great on the 2026 Toyota Camry XSE Premium Plus package. Had to use the always on hidden plug located above the light fixture, tucked into the track where the main wiring harness runs, to enable parking mode. But once I pulled the interior light and located the hidden factory dash cam plug-in and recharged my battery because it dropped below the 12.4V setting, everything works well. Would recommend. Again you must use the hidden plug in the compartment that holds the interior lights, not the plug-in for the front mirror.
Was so easy to install!
This is an excellent gadget. I appreciated how simple installation was. It spared me hours of extra time required to run cables on my brand-new car, a task I would do any thing to avoid. It is a great invention. I enjoy it, particularly the customer service, because the first unit I received had a problem and i they sent me a replacement in no time. Highly recommended.
I have a 2026 Toyota Sienna with a three-channel Viofo A229 Plus setup, bought for its clean install and parking mode support.
I first used the 10-pin harness that taps the plug behind the rear-view mirror. It allowed parking mode but made my dome lights buzz when switching on and off. The 5-pin 5A harness, connected to an unused plug behind the dome light, fixed it.
A PSA for Toyota hybrid owners (and possibly other makes): don't expect much from parking mode. There's no alternator, and the smart charging system only holds the 12V battery at 12.7-12.9V while driving, though it will charge while parked with ignition on. If a cutoff drains the battery to 12.4V, it may never fully recover without a tender or long ignition-on stretches. The battery is also at the rear of the Sienna, so expect 100-300mV of voltage drop. Set the Dongar Pro+ cutoff lower than your target battery voltage to compensate.
This is a hybrid quirk, not a product issue. I'm very happy with the Dongar Pro+.
