Some have the 4 pin, they have a bunch of different models. I can confirm this one works for AP1 S2000's: https://www.aliexpress.com/item/1005...3ea7f19c8Q4Q9e

I can't get the TP link bluetooth module going. Seems you need to download drivers on to it which are only available for PC and not Mac. The UBT module it comes with seems to be stable now. I'm guessing it's a bad connection, I'm going to tape it and see if that helps.

 

Last update from my end. The connectivity issues have been resolved. For anyone looking for an AP1 bluetooth option in the future, I can share that the Yatour M06-HON1 can work seamlessly if you replace the bluetooth module. and the connection has been rock solid.

 

Also reporting back, the GROM unit is installed and it works really well. We zip-tied the grom box under the driver side dash in an elegant way with two zip ties. You can’t see it, and there is no tension on the wires. It looks OEM. This set up also allows for easy access to the GROM box if needed.

All the dash audio controls work exactly as expected. The sound is very good to me, definitely better than the radio.

So far the only two negatives I can tell are:

1) a mild low volume speaker “pop” when it connects for the first time. Do you know what I mean?
2) A couple times while driving the BT disconnected and I had to reconnect. I’m not sure if it’s because of siri reading map directions or what, I’ll try to figure out a pattern as time goes on.

Really happy with it so far!

 

Thanks for the link! the model i found had a 4 pin, didn't see the one with the USB input!
