All Speaker Bluetooth Audo, DAB & Telephone?

[oovavoo]

Hi all,

I am a new owner of a 2013 (63) Astra J Elite. Now, the issue has come already that the car lacks anything bluetooth and also DAB. Now, DAB i can live without, but the bluetooth telephone / audio i cannot. FM just does not cut it for me.

What I am trying to achieve is this:

Telephone calls over bluetooth (using steering wheel controls)
Bluetooth Audio - iTunes Music subscription
DAB+ for Kisstory mostly.

I have got rear sensors but i have been looking at a couple of products to try and achieve this, but not really sure if it will all work, or what other options there were?

Part 1 - AutoDab CTDAB-VX2 - https://www.bassjunkies.com/ctdab-vx2.html
This will give me national DAB+ without any problem and all the stations i am answer, which is great.

Part 2 - RetroFit Ray Smith Bluetooth for CD400 - https://www.raysmith.co.uk/vauxhall-oem-bluetooth
This will give me the phone facility and steering wheel controls, but ONLY front speakers for A2DP, which is poor considering I want full car audio.

What can i do / fit / get fitted which will give me DAB and Phone and BT Audio across the whole car. I appreciate Phone will most likely be front 2 speakers and thats fine, but I need help please if anyone can assist???

Thanks,
Sean
