about a 30-min install procedure, once you have the connector spliced into the headunits loom. Leave your vehicle's stock connector untouched..don't cut it !!
If it's just a simple head unit install then I would recommend having a crack at it yourself. You will learn some new skills and save yourself some coin in the process.
I would be more than happy to point you in the direction of all the components you need along with some DIY steps.
One thing we would need to know is do you have the RF system in your car or not?
