I swapped out my stock car radio in my Toyota Avalon with a Sony XAV-AX100 Android Auto head unit which I also have installed in my other car.
It’s amazing what a difference it made to the radio reception. I can now clearly receive many low power and Wollongong/Central Coast stations which I just wasn’t able to receive before.
The stock radio wasn’t exactly a shitty unit, either. It had very decent audio quality for a radio from 2000, but only in good reception areas. I initially thought it was an antenna problem because the stock radio often wasn’t able to lock onto stations like WSFM and 2DAY with auto-seek mode, even in the centre of Sydney.
