The car came with a perfectly adequate sony CD/Analog Tuner/MP3 USB single din unit however the goddess of temptation is pushing me to invest in a replacement unit with Bluetooth - so I can stream spotify or anything from my mobile phone and also answer calls 'handsfree'.
Saw this sony mechfree DSXA50BT unit that will be on sale tomorrow at Repco at around half RRP / half JBhifi pricing (I realise it's a 2013 model).

Reviews for this model seem ok, and I'm predicting the harness will be directly swappable with my existing sony headunit - so in theory it will be a 10 minute upgrade job




But I haven't listened to DAB+ audio, is it a worthwhile investment and should I save up for those models with DAB+? Can't it all be streamed via app through 3G/4G? I was considering a double din unit with integrated GPS maps but I am thinking this mechless BT unit might just be sufficient, and I use the mobile phone for navigation. The mechless unit is a shorty without CD mechanism (saves weight because race car) and probably consumes less power and less mechanical things to go wrong I'm assuming. The current sony has red instrumentation whereas this mechless unit is white & blue, my only gripe as it won't match the NB8B dash :S
Anyone have this unit or similar unit would like to comment? Thanks!
