What is it?

A Bluetooth auxiliary port bridge for vehicles without wireless connectivity. There are occasions when taking a road trip with friends can quickly turn sour, not least when you find yourself at the mercy of their heinous CD collection because their car doesn't have Bluetooth.

With Apple's new iPhone 7 following a new trend and omitting the headphone jack to accommodate a bigger battery, this is something which will further compound the issue.

What can you do short of buying a new car? The answer is a device like the iTrip Aux Bluetooth from Griffin which turns your car stereo into a wireless system.

Good points?

Installation is simple and done by plugging the device into the 12-volt power adapter and then connecting it to the vehicle's auxiliary port via the supplied cable. The whole set-up and pairing process takes less than a few minutes. The iTrip Aux Bluetooth will also remember your device for future automatic connection which is a nice touch. Griffin's warranty guarantees the device for life due to how well it is manufactured. Should the gadget fail, they will either repair or replace without hassle.

Bad points?

None identifiable. It does what's expected of it.

Best for ...

Those with older cars who have their music library on modern smartphones.

Avoid if ...

The idea of allowing someone else access to your speaker fills you with dread, especially if you are a closet Belieber.

Score: 10/10
