Oh it’s a thing alright.
Up for grabs:
I had this for roughly a year and sold the car it was in.
* Sony XAV-AX100
* IDatalink Maestro SW (reprograms your radio controls on your steering wheel if you have them) I guess it works on all cars?
* Receiver Harness adapter (if I recall it’s the Metra 70-17121) pre-wired to the radio harness by crutchfield. I can double check the number.
This was in a Honda CR-V. I installed this radio and steering wheel control adapter about a year ago, so I pulled it out. I lost one mounting screw a (5mmx8mm) when I took it out. This is probably easily bought at Lowe’s, etc. CarPlay froze a few times over the year but I attribute that more towards Apple than the head unit. The Maestro is really cool as you can reprogram your steering wheel controls. It was a pain to figure out how to get it wired though. It all worked great when I took it out of the car. I don’t know if it fits your car. Check Crutchfield for comparability.
I am looking for tools or fishing junk.
