Connecting your iPhone to your car audio system does not have to be difficult. Most new cars make the process very easy. Even if you have a very old car, there are still accessories you can pick up to listen to your iPhone/iPod music in your car. These Cassette Adapters for iPhone come very handy in cars with an old cassette system:
iDeck Integrated Car Cassette Adapter for iPhone 4: does not work with all cassette systems as it does not rotate. Nevertheless, it lets you connect your iPhone to your car system without major issues (as long as you have a compatible system).
Monster iCarPlay Cassette Adapter 800 for iPod and iPhone: we have had success with this when using our older iPhone. It is lightweight and easy to carry around.
Philips USA PH-62050 Cassette Adapter: this worked great for our classic iPod. It is quite affordable and does what it promises. It is compatible with your other mp3 players.
Let’s face it. Most new cars come with advanced audio systems well capable of handling your iPhone, iPad or iPod. But if you love your old audio system in your car, the above cassette adapters can do a decent job connecting your mp3 players to your car’s audio system.
