I thought I'd update this thread.
I just bought an RS 60 and have decided to retrofit PCM 2.1 for the CDR-24.
I decided to do this for a number of reasons.
1) I am put off by an aftermarket install kit because my car has BOSE and in order to retrofit I would have to pay nearly $900 for a kit to work with the BOSE amp. I think the BOSE stereo output is good and I can't justify an aftermarket amp or an install kit with that price tag. I addition to the install kit, I would of course have to pay for the aftermarket radio. Plus side of this is far more advanced head unit with a bunch more functions, but I really only need iPod. XM would be nice as thats not an option currently for the PCM upgrade below.
2) Although I find PCM 2.1 to be a bit clunky, the reason I like it is the obvious factory look and the fact that with some extra equipment, i can add bluetooth and iPod and access it through the factory controls.
So I have a PCM unit from an eBay auction and I'm now looking into the bluetooth interface. A number of our 2008 cars that come in off lease have a Tooki unit and it works pretty well. While its a perfectly functional system, i think they're more expensive and use slightly older technology.
I'm considering a MoBridge adapter or the new Denison Gateway thats available in 1-2 weeks. I use an iPhone 4S exclusively and want the best possible interface for iPod control. Bluetooth quality is important but I wouldn't be swayed by how they rank unless one unit was terrible.
Does anyone care to comment on MoBridge or Denison units? Likes / Dislikes?
