First post here but looking forward to getting to know you all and hopefully have a crack at resolving an issue I’ve been experiencing for some time.
For some background, my vehicle is an 2016 A180d (65 plate) that originally did not come with the Android Auto/Apple CarPlay software...
I currently have a 2007 C180 W203 (Passed Down by the old man) :o.
I was thinking of changing the sound system, starting with the head unit, the current one is an Audio 20 without Bluetooth, aux or ipod etc.
Is the Pioneer Avic F70Dab ( link below )...
Model: C220 CDI
I have a
Type: Audio 10
Model: BE 6019
MB Part#: A 203 820 16 86 
Today whilst cleaning the car.. i got carried away and pulled out the centre console because i wanted to see if i could add an aux in for a 3.5 mm jack.
I recently bought a lovely 1994 E320 Coupe which i am very, very happy with. I've wanted one ever since I sat in my Mum's when I was, sadly, much younger.
One small problem I have is that that stereo is broken, both a faulty head unit and a non-ejecting cd cassette in the boot...
Standard Audio20 from a 2006 C-Class in good condition (works perfectly). I've got it listed on Ebay, or send me a message. Note - it's in Australia, so there's no snow damage :D
