hiya mate just my 2cents
i got an alpine headunit + steering wheel remote adapter for clio
when i bought it they guy said it would be cheaper to get the steering wheel adapter for jvc kenwood and pioneer as they do oem steering remote adapters where as alpine only do theirs and my alpine one cost 75 notes just for the adapter OUCH!!! they did fit it for free though which was handy as dash has to come off for that so saved me some time and swear words
apparently he said the oem adapters for other brands cost around 45 notes so its a bit of difference
best bet is ask questions before you buy ie find the one you like then ask in a shop etc if they can get the steering remote adapter for your clio and that headunit
