hi ! i just discover that the sony xperia x tablet have a built in radio FM with RDS ! i know it is too big for your car but i noticed it ! we should make a list here with all the tablet android with radio FM ! it should be useful ! i also own a smartphone with radio FM (little screeen xperia sola) but if you need a bigger screen, you should look at 2012 xperia product from sony. it is a shame, but i also discover that last smartphone from sony (xperia z) DID NOT have the radio FM !!!! what a big shame from sony ! it was a long time i search for a tablet with radio FM, but i did not find one which can wake up (switch on) and play radio (like a radio alarm). Even it you install tuneradio application, you have to remain you tablet in sleep mode, so battery is dicharging too. Still searching !
