Its all about the area you're in and the kind of threats you're facing, but get on the radar forum or search Vortex radar on youtube for a model rundown. I use a quadlock mounted to the steering stem, you lose some dash real estate but its a good tradeoff. Most important is getting the sound alerts to your helmet.and having a warning light. For my unit (Uniden R7) sound I use a Sena and BT transmitter (some RD's have built in BT), for the dash light I built a small circuit with LED's that took the data output from the RJ11 lead and turned it into flashes. Pretty sure the escort redline has built in BT and you can power the LED's from the sound jack, you also want an RD with GPS for fixed cams and locking out falses. RD world can be pretty geeky but get one of the top end units with a compact form factor and good connectivity.
On the Pani there is a switched accessory lead under the front fairing, pretty sure I used this to power a small relay with the RD's power coming from the battery.
