I used an Intel 2011 access point with a crossover cable straight into the back of the empeg. I power both the empeg ignition sense and the Intel AP via a relay which is controlled through the Clifford Alarm. This way when I want to sync, press the remote button on the alarm, both the empeg and AP power up. The AP takes about 15 seconds before I can associate with it but then I have have full sync and ftp,http...

I found that in my old car, if you have the AP on all the time the battery will drain to a nonstarting level in about 3 days. So a remote power up method is a good thing.
