Just purchased an Evo Start LTE all in one kit. I'm installing in a 2008 Cadillac CTS, and ran into trouble when setting it up with FlashLink. Stepping through the steps for an initial flash, I come to "RF Kits" and it asks me to select a RF Kit or a smartphone app. I plan to use both the Start LTE and an RFK441 setup, but the software only allows one selection. What should I select and flash? The instructions for the start say to program the RF Kit first, disconnect, then do the Start LTE, but no mention of what to select in FlashLink. Thanks in advance for your help!
