You can certainly integrate the V1 plus a concealed display with the Cheetah GPSmirror or Cheetah C100.
We do make a laser jammer interface for the LI as well, so you could have all three products alerting as one completely integrated system. However, Cheetah interface for the LI does not support the LI voice alerts and that's a pretty cool feature on the LI so you may prefer to run the LI as a stand alone jammer, but the option does exist. One advantage of using a Cheetah interface on the jammer part is that is makes it wireless, and therefore much easier to instal.
In comparison to integrating the V1 with the LI, integrating with a Cheetah gives you more features, better features and it's much easier to do. Basically, LI Integration gives you voice alerts. Cheetah integration gives you nicer voice alerts, false alarm suppression, band control, Radar Muting, a discreet visual display and City Mute so you can swap between voice only alerts or voice plus tone. Everything on the Cheetah solution is plug and play so it's much easier to do yourself. Cheetah's is the only method of reducing the false alarms from the V1 on the market, plus it deals with the photo-radar cameras at the same time.
There are not many easy ways to get GPS alerts for cameras on an in-dash navigation system. On most of the factory OEM installed systems it's not even possible. If you do attempt it, please post how you got on. It's not going to be easy and certainly not as easy or hassle free as plugging a cheetah detector into your PC and pressing a button on our software program.
As regards the wish list in your signature, there's not likely to be any good solution that integrates radar detectors successfully with installed GPS systems for a long time, if ever, so your wish list may be unfulfilled for a number of years yet, I'm afraid.
In summary, to enhance your Valentine One, there's no better option out there than the Cheetah kit. That's why we build it in the first place.
There's even a package offer available on the C100 that will help with your budget. (It's not available on the mirror): C100 & V1 RDI product page
