Public Service Announcement - How to Eliminate Hiss with Dasaita Unit on JBL Tundras

I purchased the G13 Dasaita Android Head unit for my 2018 Tundra Platinum with JBL. Specifically, this one:

$577 Dasaita Android 13 Radio for Toyota Tundra 2014-2021, 10.2" QLED Touchscreen, Wireless CarPlay, Android Auto, 5G WiFi, 4G LTE, DSP, GPS Navigation, 6GB+64GB

Fit and finish were great, and I loved the new screen and CarPlay, except I had an issue, I could could hear a hiss/static when there was sound playing and the volume was quiet, like when a music track or podcast first comes on without sound. If you listened carefully while there was sound too, you could make out the hiss.

Some people might not notice, but I am sensitive to that kind of stuff, and it was driving me insane. I looked on the forums here and reddit to find a cure, with no luck. I tried to adjust the internal amplifier gains in the factory menus, played with the DSP, no luck. I double checked the ground on the unit using a multi-meter, and it was perfect.

I was in a tough spot, and thought I'd have to make a tough choice to keep the unit and live with the hiss, or return it. I reached out to Dasaita via e-mail and they told me there is an additional harness to buy if I have an amplifer. They sent me the link to the page on the site, but it was double the price of the same harness on their Amazon store, so I purchased it from Amazon.

This cable harness can be purchased, and put inline with the harness that comes with the head unit. You connect the RCA cables to the ones coming out of the head unit, very simple.

Once this harness was installed, my his went away completely. It appears that its bypassing the internal amp on the head unit, and sending the unamplified signal to the JBL amp. I suppose another option could be to just eliminate the JBL amp by making a bypass harness, and power the car speaks with the head unit in some way, but that's a hell of a lot more work than getting this harness off Amazon and plug and play.

Just wanted to pass off for others learn, and hopefully find if they search for keywords.

 

Hey there..I have an 18 tundra too. By any chance so you remember if you use the rp2 or rp5 box? I tried both and seems like they both work

 

Unfortunately, I don't remember which box I used, sorry.

 

That’s interesting. At one point I had my stock head unit wired into a line converter from audio control. No amount of tuning would get rid of that hiss and I ended up getting an aftermarket head unit. Supposedly the Toyota head units just put out a dirty signal, but I wonder if I just needed something like this all along!

 

Wish they have 1 for the non jbl...i tried this and static noise went away but also volume suffered..cant here anything till im up to 15 on volume..

 

I don’t have my Dasaita anymore, but I think there is a setting in the radio to select if you’re using the factory amp or not. That should adjust your volume issue.
