the part people aren't thinking about. Network access providers are moving to data plans vs unlimited data. So as cool as this stuff is - most people will find they do not want to run these data intensive services on their data plan. A case where the tech has out paced the services.
I'd agree here, although audio isn't how you burn GBs of data per month. Say I listen to 128kbps audio streamed over 3G, for 4 hours a day (2 hour commute each way). After 30 days of this, I've used ~105MB, plus maybe 10% for overhead. So call it 120MB.
In the US, the main data plans start at around 1GB per month. Being a fairly heavy user of something like this isn't gonna trash your data plan. Especially if some of the streams are offered in 96kbps for talk radio. It might if you listen 8 hours a day over 3G and don't have wifi access anywhere you are (~250MB/month). But video is the real way you destroy a data plan and rack up overages. Some websites are worse for your bandwidth than streamed audio.
I would think its the SAME head unit, but you can reFLASH the system using the SD card SLOT ?
It is a different head unit. It's a 6" touchscreen Double-DIN versus the 7" touchscreen larger-than-Double-DIN monster in the existing vehicles.
