Retrofit Handsfree / bluetooth to 2008 Jetta in 2016 or new head unit ?

[Sehr Gut GTi]

Good Morning Folks,

I have searched the threads and previous posts on Bluetooth handsfree and headunits for my 2008 Jetta Tdi seem to be several years old. I'd be grateful for any advice.

I would like to add the following abilities to the car
Handsfree for my car with steering wheel controls enabled (I have a red MFD if that helps)
Be able to stream music through the sound sytem from my Samsung Note 3 phone using spotify if possible or use a service of the phone similar (my phone has songs on it from spotify).
My ipod does not charge as Apple change voltage of new iPods compared to connector installed so if you guys recommend a head unit then one that will either charge a current model iPod or except a usb would be nice.

I have seen ebay advertise various head units with GPS and bluetooth etc not sure if anyone can recommend a model or advice on suitabilty.

Finally if anyone can recommend an installer in Melbourne or can I do it myself or dealer job ?

Cheers for any advice
