i have 2 xpr 6550s one 450-512 and one 403-470. the back light on the 450-512 radio is much nicer and the keypad also lights up. the back light on the 403-470 isn't as bright and the keypad doesn't light up. Is there a problem with the 403-470 radio, the seller i bought it from said it was new old stock.
