Your pm's are working because three went to KSman @ 10:57, 10:58 and 11:00. I called the number that I email you for Will @ H&H Distribrutors and I'm waiting on a response from Will to make sure the information is correct. The navigation radio has to be hardwired in the prgramming, mine was the first that Will had done as for as hardwire programming and it works perfectly. When I send him the radio I Had a checklist of what I wanted programmed in the radio as far as steering controls, how many buttons, subwoofer, dvd player, rear entertainment, SR (satellite radio), AUX, Logo, display lighting, THX and the serial number of the radio plus the production date of my vehicle. Vehicle Speed Sensor (VSS) have to be hardwired (H/W) in the programming for your vehicle to have realtime GPS position if not it will update every four to five minutes which is not good. The radio gets its timing from the GPS so there is no clock to set.
