V1 has an upgrade available. Put in your 10 digit serial number.
http://www.valentine1.com/Upgrade/ I believe it's 189.00 for the upgrade. If you put in your serial number it will tell you what the upgrade is. But I don't know if it addresses the lane assist or blind spot issue. I will be sending mine after this weekend. I need the V1 for a 4 hour drive so I cant send it any sooner.
