2001 to present (Trafic II and Trafic III). Renault Update List, Tuner List, Renault Radio Connect
My Vivaro looks identical — same method? Largely yes. Vauxhall Vivaro and Nissan NV300 of the same generation are rebadged Trafics and use the same head unit hardware.
The radio locks every few weeks in my van That is a permanent live problem. Check battery condition, terminal corrosion and any aftermarket kit drawing from the radio's feed.
Can I read the pre-code without pulling the unit? On Trafic III Tuner List units, sometimes — hold button 6 with the radio off. On Trafic II, expect to remove it.
