Blue tooth...
The Forester arrived in the land of the Vistula River with a highly advanced car audio system. Unfortunately, the level of sophistication was negatively correlated with the car’s age. And so, the CD changer module integrated with the Clarion navigation system (which must have been a futuristic device some 20 years ago) was replaced with a modest storage compartment, and the radio was upgraded with a Bluetooth dongle. That was the best 50 PLN I’ve ever spent, without a moment’s hesitation. It was completely plug-and-play with the factory unit, powered via quick-connects from the cigarette lighter wires, and with the AUX option added to the radio settings, the driving experience improved tremendously. The only thing I regret a bit is not trusting Chinese technology enough to buy the version without a microphone.
