Lots of discussion out there... but I've finally found a complete system from a 2018 model. Is it true I can replace my hardware to get working carplay?

Has anyone here actually completed this swap?

I' too, have not seen anyone post on converting, probably due to the sheer cost and potential issues; however, from the 'Zine site, user hrpuffnstuff12 says:

"Retrofitting is possible but there are multiple components that would be required and it would not be cheap to do:

1 - Replacement Navi - The new navi's (while same shape and size) have different hardware allowing CP/AA
2 - Replacement upper display - New system uses a different upper display resolution (required for CP/AA)
3 - Replacement jog knob - Not 100% necessary as old jog will work, but buttons are mapped differently. You can still launch smartphone by pressing the Audio key.
4 - New Tuner - Tuner is changed from 18M. the 17M Tuner will not allow XM access. Again not necessary for CP/AA
5 - New CP/AA box - There is a specific box that handles the heavy lifting of the CP/AA that goes between the Navi unit and USB (there are new specific harnesses for this as well) (PN-39095-TZ3-*)
6 - New TCU (AA won't work without it)
7 - New Dash harness (with new connectors) [could potentially splice your way to this]

Everything else should be carryover outside of that, but with all of that alone, its likely to be upwards of 5-6k, Additionally depending on the trim of the Head unit you get, some sensors won't (may not?) work, and the camera may not as well. "


No idea if he/she is correct, but it makes sense to me.

If I'm not mistaken, this has been discussed extensively here:


Basically, one would buy the GROM unit and not try to "port" a newer TLX system into an older model.

Thanks fellas. Upper and lower nav for sale up here in Canada for only $700, but I don't think I could convince the wrecker to pull the right items. Plus the amount of work makes it not worthwhile heh.

I don’t think anyone has mentioned programming. I’m assuming you’d have to reprogram all of the new stuff to work with your car.
