I bought the earlier version from magicshop88 that Doc had and it's worked great. Also, magicshop88 has been great for post sale support. I screwed up the software and he sent me software to reboot the unit. Siince Doc posted the newer offering, I contacted magicship88 about getting the 2010 map, and he's sending it to me w/o charge.
I have the unit hardwired to my bike for both charging and AUX so I can play music on the 4GB SD card and get voice directions via the bike's sound system. Only thing it doesn't do is provide Bluetooth sound through the sound system; at least I haven't figured out how to get it to do this. If it did, I'd buy the BOMM and see if it will work like the BOMM does with the Zumo GPS units.
Thanks to Doc for helping me with my original purchase, mounting bracket selection, and understanding how the unit works.
For $87, the newer version is an even better bargain.
