Read the post I just added. I had the same problem. On the multimedia card you made for this install go into the "Myflash" directory, then to "APL2\igo\content\voice". I deleted the mex and french files. I also deleted some other language files in:
Myflashdisk\APL2\VBT\Speech\components..I deleted all the vf_***** files. Then reuse this disk to perform the entire install again. You will now have enough room on your AVIC "myflash" drive
