Alpine CDA-9884 car stereo won't charge iPhone 4. Worked fine with 1st gen

I have the alpine cda 9853... (which is about 5-6 yrs old)... played music and charged my iphone 2g.. played music on my 3g but did not charge.... plays my music fine with my iphone 4 but does not charge . . . Which cable did you buy? Do you think the same cable you bought would fix the charging problem?

Also.. other than buying the new cable, is there another connector for that cable that would fit into the iphone 4 WITH the bumper on?

Thanks!!

While the iPhone uses a proprietary port, the cable plugs into the computer's USB port. Until last year's 3Gs Apple's iPhone connector was also compatible with FireWire. (My original iPhone came with both a FireWire and a USB cable.) I suspect your problem is the same one I had with my car adapter - the cable is FireWire based rather than USB. For me the solution was to buy a converter like this one.

Did you ever get this resolved? I have a 3GS, and other than the charging issue (I've yet to order the adaptor), I have never had a problem getting it to work with my Alpine CDA9884.
I upped to iOS4 when it came out and now I'm on 4.0.1. Head unit continued to see it, just fine.
