No You can notmarry these two radios with one control head.
The 690 is an anlog radio and the 5810 is a digital radio and there is a conflict between the two.
You can only do anlog to anlog or digital to digital single head/dual drawer or go the other way.
You can do single drawer dual head either way.
But bottom line is you cannot marry anlog with the digital.
