I had a back door dent removed from my 2017 Holden Captiva seven-seater SUV, which is just back from the repair shop. Now the radio is not tuned in.
What’s probably happened is that the battery of the vehicle has been disconnected as part of the repair process (perhaps there was some welding done, or the workshop disconnected the battery while waiting for parts to arrive). In the process, the radio’s stored stations have been lost.
This is a pretty common problem in most cars that have had their battery disconnected for any length of time, and it requires you to retune the radio to store your favourite stations. If the stereo unit is the one that came with the car from the factory, the owner’s manual should detail how to store your stations, but if the stereo is an aftermarket one, you’ll need to find the instruction sheet, or just wing it until you work out the process.
In some vehicles, you’ll also need to find the radio’s security code and key that in before the unit will even switch on.
