scsi

I've had my 05 xB for a while now and have had an aftermarket pioneer deck in it pretty much since i bought it. i've decided to go back to stock (T1804) and swapped it in tonight. i love the simplicity of the OEM unit, but it is hideous lol. i would like to stick with an OE pioneer/scion deck.

i found a great list to get started from on a 4runner forum:

and a little more digging also revealed the T1814, T1815, and T1819. Are there any others that I'm missing?

it seems that they're all plug and play, but do they all mount the exact same way or can the same mounting hardware be used from my T1804?

if these are basically my only options, I think i've narrowed my search to the T1809 and the T1814/5. can anyone verify that the there is no difference between the T1814 and T1815? if there are differences, what are they?

seems one major difference between the 09 and 14/15 is the ipod interface. the 09 uses the larger harness for which i've found direct plugs on ebay. has anyone tried these? will it work fine with my iphone 4s and charge too?

sadly, this link to a similar product seems to indicate that it will not charge...

are there any similar products to the new style ipod harness found on the 14/15?

i previously had a sub and amp installed with my old unit and i left all the cabling in just in case i wanted to put the aftermarket deck back. both the 09 and 14/15 appear to have RCAs for a sub, but how do i connect the remote turn-on for my amp?

thanks!!
