Yep, SE gets the Dolby system. It's the HU-803 or later HU-850 head units you need to be looking out for. Also available with an optional boot mounted sub-woofer if you need a bit more bass.
Up to 07 models the SE spec should have the Dolby system. It is easy to spot - if it has a 4 or 6 disc CD changer it will have it. After 07 they messed around with the specs and all became SE's with some sort of suffix, i.e. SE Sport, SE Lux etc.
