I'm going to be in the minority here but I had a head unit repaired and reworked to include differing types of cables including the addition of a 30 pin IPod dongle. The workmanship seemed spot on and I was very pleased initially but it soon became apparent there were problems with the iPod adaptor. Eventually under closer inspection I found the male 30 pin to be a n indoor snap together connector thus allowing water and debris in which corroded the internal circuitry. I wrote Iron Cross a pleasant letter explaining how pleased I was with the unit however I would like to purchase a replacement dongle that I could cut and solder in as I didn't want the down time of the head unit removal. My response from them was a single sentence stating " We switched vendors, you need to send the unit in".
Although they may have made things good in some way, I didn't bother reading their response past the " we didn't change vendors due to defective parts" after sending them a scathing reply as to what I thought of their customer service, their inability to provide an alternative solution to head removal and their reluctance to admit installing a substandard indoor connector on an outdoor unit to begin with. I ended up going a more expensive, but different route with the unit due to my displeasure with their customer service
All said, with the overwhelming responses being favorable, as a new customer I wouldn't hesitate having them rework a unit. I however will not work with them again.
I'm getting old and crotchety.
