V1 is approximately on par with 9500ix overall performance wise when you average out the sources, possibly a little bit better (arguably) and has arrows to help you determine where the cop is. Also has a strong rear facing sensor I believe. As I’ve said, I’ve had both, arrows are very useful and are not just a gimmick, however with that said the GPS is seemingly more practical for a daily vehicle as I’ve described above. > [@Ilya"](#): > > Questions I have for those Radar’ers: > > 1. Can you leave them in the car if you aren’t worried about them getting stolen? Like on a hot July day, can I leave it ‘installed’ on my dash without it melting? > 2. How does the V1 work? I heard you get free updates for life or something? Do you send it in?

Not to mention my window is tinted so that should help ‘conceal’ it a bit more. > > EDIT: Chad, everything I read is V1 is sliigghtttllly better than the 9500ix. But the 9500ix is best in the city while the V1 is best on the open road (which is why I think I’m finally going to get one - I do a helluva lot of highway driving). > > [http://radartest.com/article\_2.asp?articleid=100578](http://radartest.com/article_2.asp?articleid=100578) 1. I’ve never heard of one melting and left mine inside no problem. 2. V1 updates are essentially you gotta buy the new one if you want the update. It costs around ~$200 to upgrade and they just send you a new one. Meanwhile you can sell the old one with ~$100 loss on ebay and buy a new one if you really wanted. Both have very high resale. --- _[View the full topic](https://forums.speedlife.net/t/radar-detectors/263232)._
