Occasionally stereos will go into a sleep mode due to overheating and need to be reset.
First, turn the van just before engine start; then using something like a SIM key, press reset for 5 seconds.
Then press the power button, and it should come back to life!
If this fails, call us on 1800 674 374 or email customercare@travellers_autobarn.com.au for more help.
