Ok so I asked the service foreman today and apparently you can fit a 2010 radio in a 2009. After evaluating the performance of the 2010 radio's AM tuner, I will decide whether or not to go ahead with the upgrade, which is apparently a trade. Apparently it runs around $1000 though. But I haven't been able to find an aftermarket radio so far that actually has a good tuner, that would be even better.
