I have placed an order for an entry-level Golf 90TSi with OEM rear sensors. However, this is just the standard sound PDC, i would like to upgrade it to a rear OPS system. I was wondering how much it may cost if i were to do it myself (i am not too great at coding) or if there are any places in melbourne who would be do something like this. Maybe you guys could also give me an indicative price for such an upgrade, both DIY and possibly through a company.

Thanks
