I've read all the messages here about it being difficult, if not impossible, to replace the stock head unit. I'd like to get an RX330 but if I can't replace the head unit I won't do it. I understand the head unit itself is fine, but it doesn't have the features I want. I have a Kenwood system in my IS300, including a Kenwood Music Keg (about 1,000 on one cartridge), and integrated Sirius Satellite Radio. I can't even imagine being without those two things, so aftermarket really is the only way for me.
Am I pretty much S.O.L. on this?
Thx
