My instruction sheet does say VFM1880. 
 Below are the questions I sent to RoadMasterUSA tech support and then their response.

 Hello,   
 The manual for the VRFM7 states the unit will only support 64, 128, and 
 512 MB USB drives. But the interactive tour description on the website 
 says that the unit will support USB drives over 1GB. What's the 
 official spec?    
http://www.vr-3.com/vr3_fmmod.html    Additionally, I have successfully played MP3 files on the unit that are 
 encoded at 192kbs without flaw. But the manual says it only supports MP3 
 files encoded at 128Kbs or less. What\'s the official spec?   
 Did I get the version that has the latest firmware upgrade?   
 Thanks

 Thank you for contacting VR3 Technical Service.   
 The VRFM7 was designed to work with ANY USB Flash memory drive, 
 regardless of size. There are no OFFICIAL SPECIFICATIONS on memory size 
 or playback bitrate.   
 Our recommendation not to exceed 512 MB is based on practicality rather 
 than suitability.   
 When power is applied to the VRFM7, it always starts on 87.7 MHz and on 
 the first MP3 file on the USB drive. Even if your commute to work takes 
 45 minutes to an hour, you probably won't listen to more than 30 - 40 
 songs.   
 Why recommend huge USB memory drives that hold hundreds or even 
 thousands of songs, when each time the key is turned, the VRFM7 starts 
 at #1 again?   
 We felt it better to recommend smaller USB drive sizes. Customers might 
 have several smaller drives containing different songs on each. To hear 
 a different playlist each trip, just change USB drives.   
 The 128 KBs playback rate is also just a guideline to obtain good sound 
 quality and permit 30 - 40 songs on a 128 MB USB drive.   
 There are no new firmware updates for the VRFM7.   
 Thanks again, and good luck.
