So now I have source options... I have a 10” Lenovo tablet that will integrate with the topping and give coax out with tidal, I have an iPhone XR for Bluetooth which sounds better than the alpine if I’m honest with alac filed in music, I can also use the 178bt... but perhaps a big kick in my ass is the possibility to use optical from a CarPlay stereo in the form of a clarion nx807e sat nav, CarPlay, CD player and radio with the possibility of dab with a plug in also... apparantly clarion have ceased European sales so I snapped it up brand new very cheap... I think it’s a case of what fits where... clocks will probably be central with the double din below them and maybe the tablet in front of the steering wheel if it actually gets used or fitted permanently as it may just get a mount in front of the clocks for multi media competition use
